Step-by-step explanation:
Answer:

Step-by-step explanation:
To solve the exercise you must keepin on mind that, by definition, you have the following:
⇒ 
In the equation
you have that:
b=3
d=c
a=27
Substituting, you obtain the following:


Answer:
See below
Step-by-step explanation:
<u>Recursive Formula for Arithmetic Sequences</u>
- <u />

represents the nth term
represents the preceding term
represents the common difference
<u>Explicit Formula for Arithmetic Sequences</u>
- <u />

represents the nth term
represents the 1st term
represents the common difference
<u>Ernest's Schedule Recursive Formula</u>
We can see that the common difference is
because for each week, Ernest swims 0.25 more kilometers than the preceding one. Therefore, the recursive formula for Ernest is 
<u>Ernest's Schedule Explicit Formula</u>
Given our common difference
from earlier and the fact that
is our first term, the explicit formula for Ernest is 
<u />
<u>Denise's Schedule Recursive Formula</u>
We can see that the common difference is
because for each week, Denise swims 0.5 more kilometers than the preceding one. Therefore, the recursive formula for Denise is 
<u>Denise's Schedule Explicit Formula</u>
Given our common difference
from earlier and the fact that
is our first term, the explicit formula for Denise is 
The area of a square is: L *L
So: 8 * 8= 64
