28 is a triangular number because it is the sum of the integers 1 through 7. The next larger triangular number is 36, the sum of the integers 1 through 8. Therefore 26 is not a triangular number. Notice 28 = 7 times 8 divided by two and 36 = 8 times 9 divided by two. So what's the next triangular number??
