how do you solve 2i and 2ii

Answer:
15 and 21
Step-by-step 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
[tex]T_{5}[/tex] = (2 × 5) + 5 = 10 + 5 = 15
[tex]T_{8}[/tex] = (2 × 8) + 5 = 16 + 5 = 21
Given:
Tn = 2n+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
