I am a 2 digit number. I am even. My digits have a difference of 1. I am not a multiple of 5. The sum of my digits is 11. What number am I?

Is it 56?

Looks good to me.

To find the number that satisfies all the given conditions, we can approach it step by step.

First, we know the number is even and not a multiple of 5, so it must end in either 2, 4, 6, or 8.

Next, we know that the difference between the digits is 1, so one digit must be one less than the other. Since the sum of the digits is 11, the possible combinations are:

- 2 and 9 (9 - 2 = 7)
- 3 and 8 (8 - 3 = 5)
- 4 and 7 (7 - 4 = 3)
- 5 and 6 (6 - 5 = 1)

However, we know that the number cannot be a multiple of 5, so we can eliminate the combination with 5 and 6.

Finally, we need to check if the remaining numbers (29, 38, and 47) are even. We find that only 38 satisfies this condition.

Therefore, the number that fits all the given conditions is 38.
