Find the common ratio for the geometric sequence 2.5,5,10,20,...

Write the first four terms of the sequence given by an=2n+1

What is the 11thterm of the geometric sequence 1.5,3,6,12,... ?

Find the nineteenth term of a sequence where the fifth term is 1 and the common difference is -4. Give the formula for the general term.

A ball has a bounce-back ratio 35 . of the height of the previous bounce. Write a series representing the total distance traveled by the ball, assuming it was initially dropped from a height of 5 feet. What is the total distance? (Hint: the total distance the ball travels on each bounce is the sum of the heights of the rise and the fall.)
