Question

What are the next 2 terms in the sequence -9,-8,-4, 5, 21, 46,

Answer 1

-9,-8,-4, 5, 21, 46,95,159

Explanation:

We keep adding the square numbers to the previous terms

`-9+1^2=-8`

`-8+2^2=-4`

`-4+3^2=5`

`5+4^2=21`

`21+6^2=46`

The next term is
`46+7^2=95`

The next one is
`95+8^2=159`

We got this by observing the pattern
