4. For the geometric series t3 = 1, t5 = 9
4. Write S10 using sigma notation and evaluate the sum.
(Remember: In this problem there are 2 sets of answers because there are 2 possible values for r )
5. In the geometric series t7 = 4 and t11 = .0004.
a) Find r, allowing r to be complex b) Find t8, t9, t10 for each value of r
c) For the positive real value of r , Sn = 4,444,444. Find n
