Identify the wrong number in the following series.
0, 1, 1, 2, 3, 5, 8, 12, 21, 34
Show answer & explanation
Correct answer: B
Explanation
This is the Fibonacci sequence, in which each number is equal to the sum of its previous two terms.
0 + 1 = 1
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
3 + 5 = 8
5 + 8 = 13, but here 12 is given.
8 + 13 = 21
13 + 21 = 34
That is, 13 should have been given instead of 12.
