Answer:
D) 4 miles
Step-by-step explanation:
Pythagoras' Theorem:
(where a and b are the legs and c is the hypotenuse of a right triangle)
Given:
- a = Forrest Lane = 5 miles
- b = Pine Avenue = 12 miles
⇒ 5² + 12² = c²
⇒ 169 = c²
⇒ c = √169 = 13
⇒ Cedar Drive = 13 miles
Number of miles saved = (12 + 5) - 13 = 4 miles

Given:
The different recursive formulae.
To find:
The explicit formulae for the given recursive formulae.
Solution:
The recursive formula of an arithmetic sequence is and the explicit formula is
, where a is the first term and d is the common difference.
The recursive formula of a geometric sequence is and the explicit formula is
, where a is the first term and r is the common ratio.
The first recursive formula is:
for
.
It is the recursive formula of an arithmetic sequence with first term 5 and common difference 5. So, the explicit formula for this recursive formula is:
Therefore, the correct option is A, i.e., .
The second recursive formula is:
for
.
It is the recursive formula of a geometric sequence with first term 5 and common ratio 3. So, the explicit formula for this recursive formula is:
Therefore, the correct option is F, i.e., .
The third recursive formula is:
for
.
It is the recursive formula of an arithmetic sequence with first term 5 and common difference 3. So, the explicit formula for this recursive formula is:
Therefore, the correct option is D, i.e., .
