Discussion Forum : Number Series - Type 1 (Q.No. 3)
Directions to Solve
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?
Answer: Option

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.
36 - 30 = 6.
34 - 28 = 6.
30 - 24 = 6.
28 - 22 = 6.
So answer is 22.

36, 34, 30, 28, 24.
36-30 = 6.
34-28 = 6.
30-24 = 6.
Therefore 28-6 = 22.
That is 22 (B).
36-30 = 6.
34-28 = 6.
30-24 = 6.
Therefore 28-6 = 22.
That is 22 (B).

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.
36- 2 = 34.
34- 4 = 30.
30 -2 = 28.
24 -4 = 22.
The number should be 22 is correct answers.

Alternatively subtract the values by 2 and 4.

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.
6*6 = 36 34-6 = 28.
5*6 = 30 28-6 = 22.
4*6 = 24.
The number should be 22.

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.
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.

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.
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.

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.
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.
