How many of the first 250 triangular numbers are divisible by 5?
To determine how many of the first 250 triangular numbers are divisible by 5, we first note that the (n)-th triangular number is given by the formula (T_n = \frac{n(n+1)}{2}). A triangular number is divisible by 5 if either (n) or (n+1) is divisible by 10 (since one of them will be even, ensuring that the division by 2 does not affect divisibility). Among the first 250 integers, there are 50 multiples of 5 (for (n)) and 25 multiples of 10 (for (n+1)). Thus, there are (50 + 25 = 75) triangular numbers that are divisible by 5.
