PLEASE HELP! GEOMETRIC SEQUENCE! sooo lost..?
A fossil ammonite has the form of a logarithmic spiral. Yolanda, now a paleontologist, measures the distance of loops #2 and #4 along the radial line from the center of the spiral. She finds that the distances are 6 cm and 13.5cm. The fossil is in poor condition, and she cannot measure the distance of loop #3 from the center. But she can calculate it. What is the distance in cm.
Please help!
thank you ahead of time
T4/T3 = T3/T2
13.5/T3 = T3/6
(6x13.5) = T^23
T3 = sqroot(6x13.5)
