Question

What’s the 16th term for 32,27,22,17

Answer 1

-43

Explanation:

By staring at it for a while you can tell that you're losing 5 every step. You can write the succession as
`a_n = 32-5n` (please notice the first terms starts when
`n=0`, not 1!). The 16th term happens at
`n=15`:

`a_1_5=32-5(15) = -43`
