Question

Find the 6 th term from the end of the A.P : 17,11,14...

Answer 1

Step-by-step explanation:

◆ Given,

AP... 17,14,11..-40

So, now we need the 6th term from last. SO, by reversing the AP, we get;

AP = -40,-37,-31......14,17

Now, Given;

d=3

a1=-40

n=6

Therefore a6= a+(n-1)d

= a6= -40+(6-1)3

= a6= -40+5*3

= a6= -40+15

= a6= -25

★ So the 6th term is -25 ★

Answer 2

First term, a = 17

Common difference, d = 11 - 17 = - 6

Also, 14 - 11 = 3

So, its not an AP series
