PLEASE HELP What is the explicit rule for the sequence?
- 114, -109, -104, -99,

An= -5n - 109
An= -5n - 119
An= 5n - 119
An= 5n - 109

5n - 119

Step-by-step explanation:

First, we notice that the sequence is going up by 5, so we could rule out 2 answers: -5n - 109, and -5n -119 (They go by -5). Then all we have to find is the  constant, -119 or -109. Well we could rule out -109 because -114 is included in the sequence, and if we start by -109 and start counting up, we will never get to -114. So, the solution is 5n - 119

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
