I need help with this question

Answer 1

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.
