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.

I was thought the sum of last two digit number is equal to the first digit number.

All the following are satisfied the conditions except 751. So I was thought "751" is wrong.

Like:

8 = 5+3
7 = 4+3
9 = 8+1

Can we use this method. If anyone knows tell me.

8-5=3 of 835.

7-4=3 of 734.

6-2=4 of 642.

7-1 = 6 of 751 This one is wrong, because we got the result 6 instead of 5. (subtract first and last digit will get centerone as a result).

8-3=5 of 853.

9-1=8 of 981.

5-2=3 of 532.
