5: THEO = what should happen
EXP = Wha actually happens.
a = 4 first term, r = ?, T10 = 100.
Tn = ar^n - 1 formula for g.p
T10 = 4r^ 10 - 1
100 = 4r^9
Divide both side by 4
100/4 = 4/4r^9
25 = r^9 take the 9th root of both side
9√25 = 9√r^9
r = 9√25
To find the nth term
Since Tn = ar^n - 1
it's irrational
A rational number can be put over a fraction, while this number continues forever
B. 84
The scale factor is 1/12 which means to get back to the actual height, you would multiply 7x12
