Question

Given 4n+5 what is the first three terms of this sequence?

Answer 1

First three terms of given sequence are `9,13,17`

Explanation:

By putting `n=1,2,3` we can find first three terms of sequence

for 1st term `n=1`
`4n+5=4(1)+5=9`

for 2nd term `n=2`
`4n+5=4(2)+5=13`

for 3rd term `n=2`
`4n+5=4(3)+5=17`

Hence sequence would be like

`9,13,17.....`
