Solution

The correct option is A 85
This series follows a pattern,
Second term = 1st term +(1+0)=78+1=79,
Third term = 2nd term +(1+1)=79+2=81,
Fourth term = 3rd term +(2+2)=81+4=85,
Fifth term = 4th term +(4+3)=85+7=92,
Sixth term = 5th term +(7+4)=92+11=103,
Seventh term = 6th term +(11+5)=103+16=119
Thus, 85 replaces question mark.
