Answer 1

Answer:

$nth \ term = a + (n - 1) \times d \\ \\ = 5 + (n - 1) \times - 3 \\ \\ = 5 - 3n + 3 \\ \\ = - 3n + 8. \\ \\ so \: the \: correct \: answer \: is \: (- 3n + 8).$

hope you got the answer :)...❤

Answer 2

${\huge{\boxed{\frak{Answer}}}}$

In this A.P.

5,2,-1,-4,-7,......

a(first term) = 5

d(common Difference) = (-3)

Using formula

An = a +(n-1)d

n th term = 5+(n-1)(-3)

Simplify...

→ 5 + (-3n +3)

→ 5-3n+3

→8-3n
