Answer 1

First term of the given series = 4

The last term of the given series = 11

Explanation:

Explanation

Given that the sum of the series

∑⁸ₙ₋₁ (n+3)

The
`n^(th)` term of the given sequence

aₙ = (n+3)

Put n=1

a₁ = 1+3 = 4

Put n=2

a₂ = 2+3 =5

Put n=3

a₃ = 3+3 = 6

Put n=4

a₄ = 4+3 =7

Put n=5

a₅ = 5+3 =8

Put n=6

a₆ = 6+3 =9

Put n=7

a₇ = 7+3 = 10

Put n=8

a₈ = 8+3 =11

The sequence of the given series

4,5,6,7,8,9,10,11

Final answer:-

First term of the given series = 4

The last term of the given series = 11
