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
Answer:
s(r(4)) = 13
Step-by-step explanation:
Substitute and calculate:
s(r(4)) = 13
Well first you would do 5 / 30 which makes 6 then you would 6 times 3 equals 18. So she would make 18 loaves of bread.
