(19+33)Ã·2= 26

(33+59)Ã·2= 46

(59+91)Ã·2 = 75

So, 74 is the wrong term.

(33+59)Ã·2= 46

(59+91)Ã·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???
