Question

The sum of how many terms of the Ap 22,20,18... Will be zero?

Answer 1

Hi Mate

Here is ur answer...

AP=22,20,18

a=22

d=a2-a1=20-22=[-2]

as we wanna to find the place of 0 ...let we take an as 0

an=0

an=a+(n-1)d

0=22+(n-1)-2

-22/-2=(n-1)

11=(n-1)

so n=12...

therefore 0 will be 12th term of this Ap...

i hope this will help u...
