Find the 8th term from the end of the AP 7,9,11,…, 201

Text Solution

Verified by Experts

The correct Answer is:
197
Here, a=7,d=(9-7) =2 and l=201
Let `T_(n)=201, " Then " ,a+(n-1)d =201 Rightarrow 7+ (n-1)xx2=201 Rightarrow n=98`
8th term from the end = l- (n-1)d = ` (201 -7 xx 2) = (201 -14) =197`
