Answer:
Step-by-step explanation:
r = 3.5 / 0.5 = 7
t3 = 0.5 * 7^2
t3 = 0.5 * 49
t3 = 24.5
tn = t1 * 7^(n - 1)
t8 = 0.5 * 7*(8 -1)
t8 = 0.5 * 823543
t8 = 411771.5
This problem is a geometric progression. That means that each term is multiplied by a constant and the term before it to get the current term.
