8:26 PM Sprint F Exit D Question 1 20 pts Given that you have a geometric series, a20 11611.8414 and a30 12512.717 Find r do not round D Question 2 20 pts Given that you have a geometric series, a20 11611.8414 and a30 12512.717 Find a1 rounded to two decimal places

Solution

1) a20 = 11611.8414 ; a30 = 12512.717

a20 = a1r^19 ; a30 = a1r^29

a30/a20 = r^10 = 12512.717/11611.8414 = 1.077

r = (1.077)^1/10 = 1.007
