In a three digit number, the hundred digit is 2 more than the tens digit and the units digit is 2 less than the tens digit. If the sum of the digits is 18, find the number?
Let the 10 digit be x, then 100 will be x+2 and unit digit will be x-2. Their total sum of all digits equals to 18.Therefore,
x+2+x+x-2=18
3x=18
x=6
Therefore, the three digit number is 864.

Therefore, the three digit number is 864.
864
(x+2)+(x)+(x-2)
X+2+x+x-2=18
3x=18
X=6
The 3digit number is 864
