Question

find the 6th term from the end of the AP 17,14,11,.......(-40)​

Answer 1

Answer:

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 ★
