Answer:
a(6) = 37.97
Step-by-step explanation:
If the first term a(1) is 5 and the common ratio r is 3/2, then the general formula for this geometric sequence is
a(n) = 5*r^(n - 1).
Thus, the 6th term is a(6) = 5*(3/2)^(6 - 1), or a(6) = 5(3/2)^5 = 37.97
Answer: the leg x would equal 76.8, or 77 rounded. The actual number would be 76.8374908492.
It would be rounded down to 244 as its only .1 so its closer to 244 than it is to 245
