Choose the number that will come next in the following series.
2, 5, 7, 12, 19, 31, ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 50
From the third term on, each term is the sum of the two terms before it:
\(2+5=7\)
\(5+7=12\)
\(7+12=19\)
\(12+19=31\)
\(19+31=50\)
So the next number is 50.
