Finding sum of the terms

Consider the following sequence, which consists of 2s and 9s only:
2, 9, 2, 2, 9, 2, 2, 2, 9, 2, 2, 2, 2, 9 ...
A single 9 separates each group of 2s, and each group of 2s contains one more 2 than the previous group of 2s. What is the sum of the terms that precede the 29th 9?

Preceding the 29th 9, there will be 28 9's and the number of 2's is:



Thus, the sum S is:
