Question

In the series3, 11, 23, 39, 59, ..........the next term will be(1) 63 (2) 73(3) 83 (4

Answer 1

(11 - 3) + (23 - 11) + (39 - 23) + (59 - 39) + (? - 59)

8 + 12 + 16 + 20 + next number will be 24.

So In the series, next number will be 59 + 24 = 83.

Answer 2

I hope this answer will be correct......
(3) 83
Because first and second term difference is 4, next two term difference is 12, this way 8,12,16,20 &24..hence next term will be 83.
