Answer to the Riddle:
You have to closely watch the series, since the series if increasing quickly you get a hint that an exponential component would be present.
The connection between the numbers in the series is as described below;
You need to add 1 square, 2 cube, 3 square, 4 cube, 5 square….so on and so forth to continue the series.
So we can fit this into the numbers and see if it’s correct.
First number is 10, so the next number will be;
10 + 1^2 = 11
Simillary the next numbers in the series will be;
11 + 2^3 = 19
19 + 3^2 = 28
28 + 4^3 = 92
92 + 5^2 = 117
Therefor the missing number is 92.
