Sum of digits of each number is an even number except 751.

1st digit = 2nd digit + 3rd digit. 3rd digit = 1st digit  2nd digit.

We can do like this also 85=3 74=3 :::

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.

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.

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

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

85=3 of 835. 74=3 of 734. 62=4 of 642. 71 = 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). 83=5 of 853. 91=8 of 981. 52=3 of 532.

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.

How about 981 as the odd one out because it is the only number divisible by 9 others are not divisible? 
Nivetha said: (May 1, 2016)  
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.

Second + third digit = First digit.

751 & 853 are prime numbers.

Only 532 is divisible by 7. 
Anzir said: (Sep 25, 2018)  
Thank you all for explaining this.

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