1 mile = 5280 feet
81 * 5280 = 427680 feet per hour
1 hour = 3600 seconds
427680 / 3600 = 118.8 feet per second
118.8 * 15 = 1782 feet in 15 seconds
Answer:
The explicit formula

The recursive formula
for 
if 
Step-by-step explanation:
If a sequence is arithmetical then the difference between any of its consecutive terms will be constant
3, 3.25, 3.5, 3.75,

The difference between the consecutive terms remains constant so the sequence is arithmetic.
The explicit formula for an arithmetic sequence is:

Where d is the constant difference between the terms.

is the first term of the sequence.

So

Finally, the recursive formula is:
