Question

Find 5th term of 9 , 18...….

Answer 1

Heya !!



AP = 9 , 18 , ......



Here,


First term ( A ) = 9


Common difference ( D ) = 18 - 9 = 9



Therefore,



T5 = A + 4D = 9 + 4 × 9 = 45.


Hence,

5th term of the given AP will be 45.

Answer 2

Hey !!

Thanks for the question.

Given,

ap = 9 , 18 ....

Common difference = 18 - 9 = 9

a = 9

5th term = a5

= a + 4d

= 9 + 4 (9)

= 9 + 36

= 45

Hence, 5th term is 45
