89 is a prime number between 70 and 100 that has the ones digit one greater than the tens digit.

Probably 73.

Any prime number greater than 10 is an odd number but cannot end in 5 as this makes it divisible by 5. Therefore the ones digit of any prime number greater than 10 must be 1, 3, 7 or 9.

Only one positive prime number has a 5 in the ones digit. That prime number is 5. All other numbers with a 5 in the ones digit are composite because they will be divisible by 5.

The possibilities for a digit in the ones place of a prime number greater than 5 are 1, 3, 7, and 9. If a 0, 2, 4, 6, or 8 is in the ones place, the number is divisible by 2, so it would not be prime. If a 5 is in the ones place, the number is divisible by 5, so it would not be prime.

Assuming that the question refers to 2-digit numbers, the units [ones] digit must be 1 3 7 or 9 otherwise it cannot be prime. Since the two digits add to ten, the number must belong to the set {91, 73, 37, 19} The ten digit is the larger of the two so the number cannot be 37 or 19. So it must belong to the set {91, 73) 91 = 7*13 so is not a prime, whereas 73 is. So the answer is 73.
