Question

Find the first four terms of the sequence an = 4n-6

Answer 1

The first four terms of the sequence are-6, -2, 2 and 6

Explanation:

The given sequence is
`a_n=4n-6`

In order to find the first four term of the sequence we put n =0, 1, 2 and 3.

For n =0

`a_0=4(0)-6=-6`

For n =1

`a_1=4(1)-6=-2`

For n =2

`a_2=4(2)-6=2`

For n =3

`a_3=4(3)-6=6`

Therefore, the first four terms of the sequence are

-6, -2, 2 and 6
