Question #62d78

Answer 1

The equation of arithmetic sequence is below:

`A_n = (n-1)*d + A_1`

by using `a_9` = -121:
`a_9=-121 = (9-1)d -33`
`d = -22`

So we can write the equation of this sequence because we now have d

`A_n = -11(n-1) -33`

Now solve for `a_32`

`a_32 = -11(32-1)-33`
`a_32 = -374`
