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

OpenStudy (anonymous):

S, 36 is my guess. (the 36 but is not sure at all) the R is most likely. Between AD there are 2 letters, between DH there are 3 letters, between HM there are 4. So the next letter is S because between MR there are 5 letters.

Isnt it: A, 4, D, 9, H, 16, M, 25, _, _ ??

OpenStudy (anonymous):

How did you get 36?

OpenStudy (anonymous):

I think so. But that is not sure. (are u sure that u did not miss out a 9 between D and H?

OpenStudy (anonymous):

yes I did

OpenStudy (anonymous):

aha, that helps :-)

OpenStudy (anonymous):

the numbers are 2^2, 3^2, 4^2, 5^2 so the next is 6^2=36

OpenStudy (anonymous):

ah ok thanks

OpenStudy (anonymous):

I don't get this sequence either 7,2,5,-3,8,-11
