### Discussion :: Odd Man Out and Series - Find Wrong No. (Q.No.6)

Find out the wrong number in the series.

6.

19, 26, 33, 46, 59, 74, 91

 [A]. 26 [B]. 33 [C]. 46 [D]. 59 [E]. 74

Explanation:

Go on adding 7, 9, 11, 13, 15, 17 respectively to obtain the next number.

So, 33 is wrong. It must be 35

 Shanu said: (Sep 23, 2011) 19+7=26,26+7=33, the given series is 7,9,11,13...but 7 is repeating twice in the given sol..it's wrong

 Lavanya said: (Jan 10, 2012) 19+7=26, 26+9=35 but in given series they give 33 so its wrong so 33 is oddman out.

 Rathi said: (Apr 19, 2012) 19 + 7 = 26 26 + 9 = 35 35 + 11 = 46 46 + 13 = 59 59 + 15 = 74 74 + 17 = 91 In this series 33 is given instead of 35, So 33 is wrong

 Ayaush said: (Sep 15, 2012) 19 + 7 = 26 26 + 7 = 33 33 + 13 = 46 46 + 13 = 59 59 + 15 = 74 74 + 15 =89 so why 91 is not false???

 Rintu said: (Jun 20, 2013) 19+7 = 26. 26+9 = 35. Instead of 35, it given 33. So it is wrong. 35+11 = 46. 46+13 = 59. 59+15 = 74.

 Adil Maqbool said: (Aug 24, 2013) @Ayaush. There should be having some regularity in the series. Just adding 7 twice & dn suddenly jumping to add 13 twice & dn 15 twice doesn't make any sense/regularity. So 91 can't be taken as answer but 33 is the correct answer.

 Hamsa said: (Apr 12, 2015) 19-10 = 9 perfect sqr (3*3). 26-10 = 16 perfect sqr (4*4). 33-10 = 13 not a perfect sqr. 46-10 = 36 perfect sqr (6*6). 59-10 = 49 perfect sqr (7*7). So 33 is odd.

 Aadhithyaa said: (Jun 21, 2015) Hi, @Hamsa's comment: I believe 33-10=23 but you have given 33-10=13.

 Kamoo said: (Jun 28, 2016) 33 not the correct answer.

 Lakshu said: (Aug 15, 2017) I hope 33 is not the correct answer. Because subtract the digits we get the series of 7, 7, 13, 15, 17. So 15 is not a prime number. 74 should not be there. Please explain.

 Mukesh said: (Sep 11, 2017) Ans is 74. 26-19=07 33-26=07 46-33=13 59-46=13 74-59=15 91-74=17 So ans is 74.

 Jainik said: (Jul 12, 2019) (19+33)÷2= 26 (33+59)÷2= 46 (59+91)÷2 = 75 So, 74 is the wrong term.
