# Logical Reasoning - Number Series - Discussion

### Discussion :: Number Series - Type 1 (Q.No.3)

In each series, look for the degree and direction of change between the numbers. In other words, do the numbers increase or decrease, and by how much

3.

Look at this series: 36, 34, 30, 28, 24, ... What number should come next?

 [A]. 20 [B]. 22 [C]. 23 [D]. 26

Explanation:

This is an alternating number subtraction series. First, 2 is subtracted, then 4, then 2, and so on.

 Amruta said: (Aug 30, 2010) We can do it other way also as follows: 36 - 30 = 6. 34 - 28 = 6. 30 - 24 = 6. 28 - 22 = 6. So answer is 22.

 Haneeshendluri said: (Dec 4, 2010) The series is 36,34,30,28,24... Lets take difference of successive 36-34=2,34-30=4,30-28=2,28-24=4.. By observing the above differences that is clear that 4,2 are the successive differences that we are getting. So the next difference is 2,4,2,4,2,4, next number 24-2=22.

 K. Santhikannan said: (Dec 2, 2011) 36-2=34 34-4=30 30-2=28 28-4=24 24-2=22 Therefor answer 22

 Ramya said: (Apr 12, 2012) 36 - 30 = 6. 34 - 28 = 6. 30 - 24 = 6. 28 - 22 = 6. The answer is 22

 Arzoo said: (Oct 23, 2012) 36-2=34-4=30-2=28-4=24-2=22 That's right answer=22.

 Pushpendra said: (Mar 22, 2013) 36-2=34-4=30-2=28-4=24-2=22 That's right answer=22.

 Himansu Sekhar Bhoi said: (Aug 25, 2013) 6*6 = 36-2 = 34. 6*5 = 30-2 = 28. 6*4 = 24-2 = 22. In this way.

 Sanjoy Das said: (Sep 13, 2013) 36-2 = 34. 34-4 = 30. 30-2 = 28. 28-4 = 24. 24-2 = 22. Therefor answer 22.

 Bhaskarananad said: (Dec 6, 2013) 36-34 = 2. 34-30 = 4. 30-28 = 2. 28-24 = 4. 24-22 = 2. So the answer is 22 it is alternate subtraction of 2 and 4.

 Ramesh said: (Dec 20, 2013) 36 - 2 = 34. 34 - 4 = 30. 30 - 2 = 28. 28 - 4 = 24. So now, 24 - 2 = 22 answer.

 Nand Lal Thakur said: (Mar 31, 2014) 36-2 = 34. 34 -4 = 34. 30 -2 = 28. 28 - 4 = 24. 24- 2 = 22 Answer.

 Yogita Dawar said: (Apr 21, 2014) 36, 34, 30, 28, 24,..... 36-2=34. 34-4=30. 30-2=28. 28-4=24. 24-..=.. It will repeat that alternative numbers 2 and 4. then 24-2 = 22. answer is B. 22.

 Pavan Bhushan said: (Apr 21, 2014) The numbers are obtained by doubling the numbers in descending order. After every two numbers, one number is excluded. 36= 18*2. 34= 17*2. The number 16 is excluded. 30= 15*2. 28= 14*2. 13 is excluded. 24= 12*2. Next number should be 11*2 = 22.

 Vidyasagar said: (Apr 29, 2014) 36-34 = 2. 34-30 = 4. 30-28 = 2. 28-24 = 4. 24-22 = 2.

 Mms said: (Jun 19, 2014) 36-34 = 2. 34-30 = 4. 30-28 = 2. 28-24 = 4. 24-22 = 2. Just follow the series of 2,4,2,4,last is 2 ....it will get by subtracting 24-22=2.

 Ranji said: (Aug 4, 2015) Odd terms are multiple into 6 and even terms are subtracted to 6. 6*6 = 36 34-6 = 28. 5*6 = 30 28-6 = 22. 4*6 = 24. The number should be 22.

 Tulasi said: (Sep 26, 2015) Alternatively subtract the values by 2 and 4.

 A.G Rao said: (Oct 23, 2015) Add Subtracted to 6, 4 or 4 digit number but this simple logic. 36- 2 = 34. 34- 4 = 30. 30 -2 = 28. 24 -4 = 22. The number should be 22 is correct answers.

 Ashish Labade said: (Feb 23, 2016) 36, 34, 30, 28, 24. 36-30 = 6. 34-28 = 6. 30-24 = 6. Therefore 28-6 = 22. That is 22 (B).

 Rabia said: (Mar 1, 2016) Please explain in details I.

 Sweety Sharma said: (May 13, 2016) 36, 34, 30, 28, 24, _ ? 36 - 2 = 34, 34 - 4 = 30, 30 - 2 = 28, 28 - 4 = 24, 24 - 2 = 22. Ans: 22.

 Deepshikha said: (Jun 28, 2016) 36 - 2 = 34 34 - 4 = 30 30 - 2 = 28 28 - 4 = 24 24 - 2 = 22 So, answer is 22.

 Sudhansu said: (Jul 9, 2016) The given series is of -2 then -4. Therefore, the answer is 22.

 Mohd Moin Ansari said: (Aug 2, 2016) 36 - 2 = 34. 34 - 4 = 30. 30 - 2 = 28. 28 - 4 = 24. 24 - 2 = 22.

 M.Raghuram said: (Aug 24, 2016) The logic of this sum is Alternately leaving difference 2, 4.

 Aditya Vamsi said: (Aug 24, 2016) Just subtract 2 and 4 for the number in ascending order.

 Jhansi said: (Aug 24, 2016) Here, the logic is First, subtract 2 and then 4 again 2 and then 4 and so on.

 Smriti said: (Nov 4, 2016) Logic: Subtract 6 from the number and you will get the alternate number.

 Chiddu said: (Nov 14, 2016) Here is a simple logic we have to just subtract 6 from the number and we will get the alternate number.

 Tarun Mishra said: (Dec 4, 2016) Reasoning message in phone.

 Kavita Dev Sharma said: (Dec 11, 2016) I understand. Thanks all of you.

 Demullu Reddy said: (Dec 15, 2016) Very helpful for students. Thank you.

 Mahananda Mohanty said: (Jan 8, 2017) Firstly the last no of is added i.e. the sum of 6 and 4 of 36 &34 the no. Will be10 then the sum of0&8out of 30&28 the no will be8then. The sum of 4 &2 out of 24&22 the no will be 6. Due to the dressing in the given series the answer will be 22.

 Varun Ratan said: (Jan 28, 2017) 36-6 = 30 34-6 = 28 30-6 = 24 28-6 = 22 Answer = 22.

 Trisha said: (Apr 30, 2017) 36-2 = 34. 34-4 = 30. 30-2 = 28. 28-4 = 24. 24-2 = 22.

 Utkarsh said: (May 25, 2017) 36-34 = 2, 34-30 = 4, 30-28 = 2, 28-24 = 4, 24-2 = 22, Hence 22 will be the next term.

 Preci said: (Aug 2, 2017) 36-6 =30. 34-6= 28. 30-6= 24. 28-6=22. 24-6=18.

 Ujjwal said: (Dec 5, 2017) 36-34=2 34-30=4 30-28=2 28-24=4 24-22=2 Here 22 will next term.

 Kavi said: (Feb 24, 2018) 36-2=34, 30-2=28, 24-2=22.

 Srisai.Putta said: (Sep 4, 2018) The given series is 36, 34, 30, 28, 24 by subtracting with 2&4 we get next number to the 24. 36-2=34 34-4=30 30-2=28 28-4=24 24-2=22. 22 is the final number which is next to the 24 in the given above series. Therefore, 22 is the next number.

 Anonymus said: (Oct 27, 2019) 3*12 = 36 3*11 = 33+1 = 34. 3*10 = 30 3*9 = 27+1 = 28. 3*8 = 24 3*7 = 21+1 = 22.

 Dhanashree Pathare said: (Jan 27, 2020) According to me, the solution is; 36 - 2= 34. 34 - 4 = 30. 30 - 2 = 28. 28 - 4 = 24. 24 - 2 = 22. So, the answer is 22.

 Lasya said: (Jun 2, 2020) The order is -2,-4,-2,-4,-2.

 V. Raman said: (Dec 2, 2020) 36 - 2 = 34. 34 - 4 = 30. 30 - 2 = 28. 28 - 4 = 24. 24 - 2 = 22. So, in this way you can get the answer.

 Dushyant said: (Jan 6, 2021) Good explanation. Thanks.

 Dinesh Bharti said: (Feb 2, 2021) 36-2 = 34. 34-4 = 30. 30-2 = 28. 28-4 = 26. 24-2 = 22. The is the correct answer series.

 Aryan Jain said: (Mar 29, 2021) 36 - 0 = 36 36 - 2 = 34 36 - 6 = 30 36 - 8 = 28 36 - 12 = 24 36 - 14 = 22.
