Question

The nth term formula of a sequence is given as Tn = 5n+1. Use it to find the first 5 terms of squence

Answer 1

The first 5 terms are
`6,11,16,21,26`

Explanation:

Given:
`T_n=5n+1`

To find: the first 5 terms of sequence

Solution:

To find the first 5 terms of sequence, put
`n=1,2,3,4,5` in
`T_n=5n+1`

`T_1=5(1)+1=5+1=6\\T_2=5(2)+1=10+1=11\\T_3=5(3)+1=15+1=16\\T_4=5(4)+1=20+1=21\\T_5=5(5)+1=25+1=26`

So, the first 5 terms are
`6,11,16,21,26`
