Question

A, 4, D, H, 16, M, 25, _, _ What are the next two in the sequence?

Answer 1

I would say that the new two in sequence are S and 36.
There are two numbers between A and D, three between D and H, four between H and M, which means that S is the fifth number after M.
I think you are missing number 9 between D and H, which means that 4 + 5 =9, 9 + 7 = 16, 16 + 9 = 25, and 25 + 11 = 36, 2 is added to each number.
