= 9n + 63
generate the first few terms using the recursive equation
f(1) = 72
f(2) = 72 + 9 = 81
f(3) = 81 + 9 = 90
f(4) = 90 + 9 = 99
the sequence is 72, 81, 90, 99, .....
This is an arithmetic sequence whose n th term formula is
= 
+ (n - 1 )d
where is the first term and d the common difference
d = 99 - 90 = 90 - 81 = 81 - 72 = 9 and = 72
= 72 + 9(n - 1) = 72 + 9n - 9 = 9n + 63 ← explicit formula
Answer:
.
Step-by-step explanation:
X 3/5 =2x+15=2x=15-2x=13
answer 13
F(-5) just means that your substituting the number -5 for every x value. So if you have x+1 this would be -5+1 which is -4
The last one- its the only one that applies to the 4* rule.
