20. Write the first 4 terms of the sequence defined by the recursive
rule. (4.1 and 14.2))
a. f(1) = 3, f(n) = f(n-1) + 4, n > 1
b. f(1) = -2, f(n) = f(n-1) -3,n> 1
c. f(1) = 3, f(n)= f(n-1).-2,n22
d. f(1) = -2, f(n)= f(n-1) -4,0 2 2

Step-by-step explanation:

Adam

Step-by-step explanation:

You just have to divide feet/second

Adam: 15 feet per second

15/1=15

Noah runs 599 feet in 40 seconds

599/40=14.9

Jake runs 1 mile in 384 seconds

1 mile=5280 feet

5280/384=13.8

liz runs 667 feet in 1 minute

1 minute=60 seconds

667/60=11.1
