Question

Which term of AP 84, 80, 76, ................. is 0 ?​

Answer 1

Answer:

22nd term

Step-by-step explanation:

The given sequence is an AP in which first term a=84 and common difference d=−4.

We have to find value of n for which a

n

is 0.

Then,

a+(n−1)d=0

⇒84+(n−1)×−4=0

⇒88−4n=0

⇒n=22

Hence, 22

nd

term is 0.
