The sum of the digits is 13.

The first digit is 2

The last digit is 0 or 5

Can it be zero?

2 + _ + 0 = 13

2 + 0 _ x = 13 Subtract 2 from both sides

2 - 2 + 0 + x = 13 - 2 Combine

x = 11

No there is no such thing as a digit is value is 11. So the last digit is 5

2 + __ + 5 = 13

7 + x = 13 Subtract 7 from both sides

7-7 + x = 13 - 7 Combine

x = 6

The middle number is 6

Answer: I am 265
