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

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.

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.

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.

Only 532 is divisible by 7.

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.

This one is more easy
3+5=8 of 835
3+4=7 of 734
4+2=6 of 642
5+1=6 of 751 This is wrong because we got the result of addition as 6 instead of 7.
5+3=8 of 853
8+1=9 of 981
3+2=5 of 532

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.

In each number except 751, the sum of 2nd digit and 3rd digit is the first one.
