there are 7 days in a week x 0.10 cents saved each day on the week = 0.70 cents every week
Step-by-step explanation:
Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.

SEQUENCE: 6, 18, 54, 162
18/6 = 3
54/18 = 3
162/54 = 3
then, r (common ratio) = 3
_________________________________________
RECURSIVE RULE: r = 3
an = a(n - 1) × r [formula]
ANSWER: an = a(n - 1) × 3
_________________________________________
ITERIATIVE RULE: r = 3, a1 = 6
an = a1 × r^(n - 1) [formula] [ ^(n-1) is an exponent]
ANSWER: an = 6 × 3^(n - 1)
.253 move the decimal 2 places to the right then you get 25.3%
