The sum of the first n terms in the infinite geometric sequence 1/4, 1/8, 1/16, ... is 15/32. Find n.
Isn't it just n = 4? Because the denominator is 32 the nth term must be 1/32 (you can check this yourself.)
Also if anyone wants to take the time out please answer my question here: https://web2.0calc.com/questions/please-help_81768 (I don't know if this is soliciting if it is then sorry.)
Hope that helps!
