$30 because if you add 30 to those numbers it would give you the next months amount.
Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
784/ 93 = 8.43010752688
93 * <span>8.43010752688 = 784</span>
