I keep getting this one wrong : (

Find the 60th term of the arithmetic sequence - 14, - 25, - 36, ...

-663

Step-by-step explanation:

The nth term of an arithmetic sequence is:

aₙ = a₁ + d (n - 1)

The first term is - 14, and the common difference is - 11. So the nth term is:

aₙ = - 14 + (-11) (n - 1)

So the 60th term is:

a₆₀ = - 14 + (-11) (60 - 1)

a₆₀ = - 663

-663

Step-by-step explanation:

an = - 14-11 (60-1) = -14-11 (59) = - 14-649 = - 663
