From what you have here, it seems that the preceding number is multiplied by 3. Looks like the 11th person gets a gigantic sum. I'll let you do the calculations.
or, the sequence is arithmetic, and grows by 150 for each person, so the 11th person gets 75 + 10*250 = 2575
S11 = 11/2 (75+2575) = _____
S11 = 11/2 (75+2575) = _____
