Question

Identify the 35th term of an arithmetic sequence where a(1) = -7 and a(18) = 95.

Answer 1

The common difference d can be found from the following formula:
\[d=\frac{a _{n}-a _{1}}{n-1}=\frac{95-(-7)}{18-1}=can\ you\ calculate?\]
When you have found the value of d, the 35th term is found as follows:
\[a _{35}=-7+34d\]
