The sum of the terms of an arithmetic sequence is

(number of terms) times (average of the terms)

If n is the average of the terms, then the sum of the terms of this sequence of 33075 consecutive integers is 33075n.

The problem requires that this sum be a perfect cube.

The prime factorization of 33075 is

For the sum 33075n to be a perfect cube, the exponents on all the prime factors of 33075n must be 3. So we need one more factor of 5 and one more of 7 to achieve that.

So the least positive average of the numbers that makes the sum a perfect cube is n = 5*7 = 35.

ANSWER: 35
