Question

find the 9th term of the ap 5,9,13,17.....185

Answer 1

HEY, Here is your answer,
IN the above AP,
a=5 and common difference (d)=4
So, 9th term of AP,
a+(n-1)d
=5+(9-1)(4)
=5+32
=37
THUS, 9th term of AP=37

Answer 2

Given :

5,9,13,17.....185

To Find :

find the 9th term of the ap

Solution:

AP:5,9,13,17.....185

First term = a = 5

Common difference = d = 9-5=17-13=4

Formula of nth term :$A_n=a+(n-1)d$

Substitute n = 9

$A_9=5+(9-1)(4)$

$A_9=37$

Hence The 9th term of AP is 37
