Which number is the odd one out?
9678 4572 5261 3527 7768
1.] 7768
2] 3527
3] 4572
4] 9678
5] 5261
Answer:
2] 3527
Here is the deal: The sum of the first two numbers equal the sum of the third and fourth numbers. For example, for the number 9678 – 9 + 6 = 15 and 7 + 8 = 15. This pattern is the same for all numbers except 3527 (where eight which is the sum of 3 + 5 does not equal 9 (the sum of 2 + 7).
