because every number is equal or grater than two digit but 2 is not

Answer 2

The odd mans are 86 and 5686

Explanation:

Given, two series are 89, 78, 86, 80, 85, 82, 83 and 1236, 2346, 3456, 4566, 5686.

We have to find the odd one out.

Now, 1st series – 89, 78, 86, 80, 85, 82, 83.

Take even place numbers:

78, 80, 82

78 - 80 = 2

80 - 82 = 2

Take odd place numbers:

89, 86, 85, 83

89 - 86 = 3

86 - 85 = 1

85 - 83 = 2

If we change the number 87 instead of 86 we will get the difference are 2, 2, 2.

So, the odd man out is 86.

Now, 2nd series – 1236, 2346, 3456, 4566, 5686.

The sum of all the numbers in this series is multiple of 3 except 5686

1236=1+2+3+6=12

2346=2+3+4+6=15

3456=3+4+5+6=18

4566=4+5+6+6=21

5686=5+6+8+6=25 But here 24 is correct answer

Hence, the odd mans are 86 and 5686.
