Question

I am having trouble with this. Can anyone help? This question is asking me to....Find a13 when a1=-8 and d=5.... It says to begin by writing out the general formula an=a1+(n-1)d.....then substitue the known values into the formula. In this case it would be a13=-8+(13-1)(5).

Answer 10

\[a_n = a_1 +(n-1)d\]
So:
\[a_{13} = -8 + (13-1)(5)\]
