Question

Find the 9th term form the end (towards the fist term) of the Ap 9,13,185

Answer 1

Answer:

here's your answer

Step-by-step explanation:

Common difference, d, of the AP = 9

- 5 = 4

Last term, I, of the AP = 185

We know that the nth term from the end of an AP is given by / - (n-1)d.

Thus, the 9th term from the end is

185 - (91)4

= 185 - 4 x 8

= 185 - 32

= 153

Answer 2

Answer:

Here, nth term is=a+(n−1)d

=5+(n−1)4=185

n=46

46-9+1= 38

9th term from end will be the 38th term of this A.P

= a+37d

a = 5+37×4

a = 153
