Answered by DelcieRiveria

Answer:

The correct option is b.

Step-by-step explanation:

The sum of an AP is defined as

$S_n=n^2-2n$

We have a formula,

$a_n=S_n-S_{n-1}$

$a_5=S_5-S_4$

$a_5=5^2-2(5)-(4^2-2(4))$

$a_5=25-10-(16-8)$

$a_5=15-8$

$a_5=7$

Since the 5th term is 7, therefore the correct option is b.
