I know that the following is TRUE:
The average of an even number of consecutive terms (integers) CAN NOT be an integer. e.g. 1+2+3+4 = 10, av is 10/4 = not an int.
But is it TRUE?
The average of an even number of consecutive terms (integers) CAN NEVER be an integer.

I'd say yes. however, the average is always the middle term in a set of evenly spaced consecutive numbers, in some cases an even # of terms will produce an integer.
10 20 30 40, avg = 25
1 2 3 4 5, avg = 3
3 6 9 12, avg = 7.5
-3 -4 -5 -6 -7, avg = -5
101 111 121 131 141, avg = 121
hope this helps
