We can also do it like the addition of last 2 digits is equal to 1st digit. For eg.
835: 5+3 = 8.
734: 4+3 = 7.

Can we also do it like this? Addition of All the digits are even except 751?

According to me, 532 is the answer because it is the only number divisible by 7 among all.

751 & 853 are prime numbers.

Second + third digit = First digit.

8 - 3 = 5
7 - 3 = 4
6 - 4 = 2
7 - 5 = 2 is wrong answer
8 - 5 = 3
9 - 8 = 1
5 - 3 = 2

So the wrong term is 751.

How about 981 as the odd one out because it is the only number divisible by 9 others are not divisible?

8 - 5 = 3 835.
7 - 4 = 3 734.
6 - 2 = 4 642.
7 - 1 = 6 751.
8 - 3 = 5 853.
9 - 1 = 8 981.
5 - 2 = 3 532.

In this number series 751 is odd because in other numbers the 1st digit is find out by adding 2nd and 3rd digit simultaneously, but in 751 it is not happening.
