Question

How do I write the first six terms for this sequence?

Answer 1

Step 1

Given;

`\begin{gathered} a_n=2n^2 \\ n=1,2,3,4,5,6 \end{gathered}`

Step 2

The first six terms will be;

`\begin{gathered} a_1=2(1)^2=2 \\ a_2=2(2)^2=8 \\ a_3=2(3)^2=18 \end{gathered}`
`\begin{gathered} a_4=2(4)^2=32 \\ a_5=2(5)^2=50 \\ a_6=2(6)^2=72 \end{gathered}`
