OpenStudy (anonymous):
so is -1250 the answer? if not could you explain how to get it?
OpenStudy (anonymous):
-1250 is the first term. S5 means the sum of the first 5 terms, so S5 = -2 + -10 + -50 + -250 + -1250
OpenStudy (anonymous):
so I just need to add them together?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
okay I got -1562. Is that right?
