Find the missing number in the series: 5, 4, 6, 9, ?
Show answer & explanation
Correct answer: B
Explanation
5 → 4 = −1
4 → 6 = +2
6 → 9 = +3
Here the sequence is: −1, +2, +3, +4
So the next number:
9 + 4 = 13
But 13 is not in the options.
Look at the second pattern:
5 + 4 = 9
4 + 6 = 10
So the next term = 10
