Which term of the A.P. 7, 13, 19, 26, .... is 97 ?

Solution

Correct Option: 2

Taking common difference d=6d=6 (from first three terms 7, 13, 19): an=7+(n1)×6=97a_n=7+(n-1)\times 6=97 gives (n1)=15(n-1)=15, so n=16n=16.

Note: The printed sequence 7, 13, 19, 26 has an irregular step (26 instead of 25). We treat it as an AP with d=6d=6, which makes 97 the 16th term.
