Question

I am a 3-digit number that is even. My hundreds and ones digits are the same and have a sum of 8. My tens digit is 2 less than my ones digit. What number am I ?

Answer 1

424 I know because 4+4=8 and 4-2= 2 so I figured 424

Answer 2

Let's start off with some key terms.

The number has 3 digits.
Even numbers end with 0, 2, 4, 6, or 8. (Obviously)

The hundreds digit and ones digit are the same.
First number in a 3 digit number is the hundreds, and the last number is the ones.

So, both of those two digits are the same and has to equal 8.

Well, $4+4=8$

The hundreds place and the ones place are 4.

The tens digit is the middle number in a 3-digit number.

 It is two numbers less than the ones digit.
$4-2=2$

The number is 424.
