Question

Given the explicit formula for an arithmetic sequence find the first five terms and the term named in theproblem.7) a=-11 + 7nFind a 34

Answer 1

Here, we are given:

a = -11 + 7n

Let's find the first five terms:

First term:

`a_1=-11+7(1)\text{ = -11+7=-4}`
`\begin{gathered} \text{Second term:} \\ a_2=-11+7(2)\text{ = -11+14=3} \end{gathered}`
