Question

C(n)=-6+5(n-1)
Find the 8th term in the sequence

Answer 1

Just replace n by 8 ===> C(8) = -6+5(8-1) = - 6 + 5x7 = -6+35 = 29

Answer 2

29

Explanation:

We have been given a sequence formula. We are asked to find the 8th term of our given sequence.

We know that an arithmetic sequence is in form
`A_n=a_1+(n-1)d`, where,

`A_n=\text{ nth term of sequence}`,

`A_1=\text{ 1st term of sequence}`,

n = Number of terms in sequence,

d = Common difference.

To find the 8th term of our given sequence, we will substitute
`n=8` in our given formula.

`c(n)=-6+5(n-1)`

`c(8)=-6+5(8-1)`

`c(8)=-6+5(7)`

`c(8)=-6+35`

`c(8)=29`

Therefore, the 8th term of our given sequence would be 29.
