(19+33)÷2= 26
(33+59)÷2= 46
(59+91)÷2 = 75
So, 74 is the wrong term.
(33+59)÷2= 46
(59+91)÷2 = 75
So, 74 is the wrong term.

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.
26-19=07
33-26=07
46-33=13
59-46=13
74-59=15
91-74=17
So ans is 74.

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.

Hi, @Hamsa's comment:
I believe 33-10=23 but you have given 33-10=13.

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.
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.

@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.

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.
26+9 = 35.
Instead of 35, it given 33. So it is wrong.
35+11 = 46.
46+13 = 59.
59+15 = 74.

19 + 7 = 26
26 + 7 = 33
33 + 13 = 46
46 + 13 = 59
59 + 15 = 74
74 + 15 =89
so why 91 is not false???
26 + 7 = 33
33 + 13 = 46
46 + 13 = 59
59 + 15 = 74
74 + 15 =89
so why 91 is not false???
