2, 4, 6, 8, 11 - which number does not belong?
Show answer & explanation
Correct answer: A
Explanation
Observe the given series: 2, 4, 6, 8, 11.
• All numbers 2, 4, 6, 8 are even numbers (divisible by 2).
• 11 is an odd number.
Alternatively, the series follows an arithmetic progression with a common difference of :
2 + 2 = 4
4 + 2 = 6
6 + 2 = 8
8 + 2 = 10 (instead of 11)
Hence, 11 does not belong to the group.
Therefore, the correct option is (A).
