18 is an even number between 12 and 29 with digits whose difference is 7. To answer this question, we start with the last part "difference is 7" and come up with a set of values that meet the need as follows: 18 29 [29 is in the set only if the question is inclusive] Now, there is only one even number in the pre-solution set and that number is 18.
