Vishal Chugh   10 years AGO

The difference between successive numbers in the series is
16 - 10 = 6
26 - 16 = 10
41 - 26 = 15
62 - 41 = 21
Thus the difference between these differences is in series 4, 5, 6
Therefore the next difference should be equal to
21 + 7 = 28
and 62 + 28 = 90

16 = 10 + 6 = 10 + 1 + 2 + 3
26 = 16 + 10 =16 + 1 + 2 + 3 + 4
41 = 26 + 15 = 26 + 1 + 2 + 3 + 4 + 5
62 = 41 + 21 = 41 + 1 + 2 + 3 + 4 + 5 + 6

Next number = 62 + 28 = 62 + 1 + 2 + 3 + 4 + 5 + 6 + 7 = 90

Then, we have 6, 10, 15, 21
So the next sequence number will be 28.
After adding 28 to 62 we will get 90.
So, answer is 90.

The difference between sequence (10,16,26,41,62....) is (6,10,15,21).
the difference between this series (6,10,15,21) is (4,5,6).
So, the difference is increasing by 1.
Thus the last difference must be 7.
