2+6+10+14+18+22+26+30+34+38=200. (show no need total 5 of these to make 100

Question

Answer me if any one know .try to solve if genius

Answer 1

Impossible.

Each of those numbers (2, 6, 10, 14, 18, 22, 26, 30, 34, 38) is of the form 4n+2 where n is an integer.

Any even number of those numbers will be of the form 4n+2 + 4m+2 = 4n + 4m + 4 which is always divisible by 4.  (n is an integer, m is another integer, exact values of m and n don't matter)

Any odd number of those numbers will be of the form 4n+2 + 2(4m+2) = 4n + 8m +4 +2, which is always 2 off from being divisible by 4.

100 is divisible by 4, so you can only make 100 with an even number of those numbers.

5 is odd, so you can't make 100 with 5 of those numbers.
