Question

What are the first 3 terms in. t(n)=-2n+7

Answer 1

The first 3 terms of the sequence
`t(n)=-2n+7` are:

`5, 3, 1`

Explanation:

Given the sequence

`t(n)=-2n+7`

Here
`n` represents any term number in the sequence

Determining the first term

substitute n = 1 in the sequence to determine the first term

`t(n)=-2n+7`

`t(1)=-2(1)+7`

`t(1)=-2+7`

`t(1) = 5`

Determining the 2nd term

substitute n = 2 in the sequence to determine the 2nd term

`t(n)=-2n+7`

`t(2) = -2(2) + 7`

`t(2) = -4 + 7`

`t(2) = 3`

Determining the 3rd term

substitute n = 3 in the sequence to determine the 3rd term

`t(n)=-2n+7`

`t(3) = -2(3) + 7`

`t(3) = -6 + 7`

`t(3) = 1`

Therefore, the first 3 terms of the sequence
`t(n)=-2n+7` are:

`5, 3, 1`
