What will come in the place of question mark (?) in the following series?
2, 5, 7, 12, 19, 31, 50, ?
Correct Option:
A
Explanation
Each term from the third onward is the sum of the previous two:
2+5=7, 5+7=12, 7+12=19,
12+19=31, 19+31=50.
Therefore,
31+50=81.
It is a Fibonacci-type additive sequence.
