The sum of the first 39 positive odd numbers is 1521.
To find the sum of the first 39 positive odd numbers, we can use the formula for the sum of an arithmetic series. The formula is: S = (n/2)(a + l), where S is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, n = 39, a = 1, and l = 77. Plugging these values into the formula, we get:
Therefore, the sum of the first 39 positive odd numbers is 1521.
