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 = 3 835.
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.

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.

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 + 3 + 5 = 16,
7 + 3 + 4 = 14
6 + 4 + 2 = 12
7 + 5 + 1 = 13 (751 is the odd one in the series)
8 + 5 + 3 = 16
9 + 8 + 1 = 18
5 + 3 + 2 = 10.
Balance all numbers are even.

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

8+3+5=16 even.
7+3+4=14 even.
6+4+2=12 even.
7+5+1=13 odd.
8+5+3=16 even.
9+8+1=18 even.
5+3+2=10 even.

751 is answer.

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.

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?
