Question

which terms of an A.P 7,3,-1,so on is -89​

Answer 1

Answer:

Clearly, the given Sequence is an AP with first term a=7 and common difference d=13−7=6.

Let 205 be the nth term of the given AP.

⇒a

n

=205

⇒a+(n−1)d=205

⇒7+(n−1)×6=205

⇒(n−1)×6=198

⇒n=34

Hence, there are 34 terms in the given AP.
