Question

How do you solve 2i and 2ii​

Answer 1

Given:

Tn = 2n+5

1. `The fifth term, i.e., n=5

Substituting the value inside the formula we get,

2(5) + 5 => 10 + 5 => 15

2. The Eighth term, i.e., n=8

Substituting the value inside the formula we get,

2(8) + 5 => 16 + 5 => 21

Answer 2

15 and 21

Explanation:

Given the n th term formula

T = 2n + 5

To find the 5 th and 8 th terms substitute n = 5 and n = 8 into the formula

`T_(5)` = (2 × 5) + 5 = 10 + 5 = 15

`T_(8)` = (2 × 8) + 5 = 16 + 5 = 21
