Find the odd number in the following?

1110, 2716, 4135, 5321 and 7145

Share it when you get it.

Answer:

If you go through the sequence you will see that the numbers add up to be a prime number.

Like;

1 + 1 + 1 + 0 = 3

4 + 1 + 3 + 5 = 13

5 + 3 + 2 + 1 = 11

7 + 1 + 4 + 5 = 17

However, in the case of 2716,

2 + 7 + 1 + 6 = 16 which is not a prime number.

Hence answer = 2716
