Bean plants grow rapidly. A bean plant is 16 inches tall. Tomorrow it will be 24 inches tall, the
next day it will be 32 inches tall, and on the next day it will be 40 inches tall. Write a rule to
represent the height of the bean plant as an arithmetic sequence. How tall will the plant be in
12 day

Here are the Questions:
A(n) = 16 + (n – 1)8; 104 inches

A(n) = 16 + (n – 1)8; 116 inches

A(n) = 16n; 192 inches

A(n) = 12n; 144 inches

since they have told you it is an AP, just look at the first two points:
a = 16
d = 24-16 = 8
So, A(n) = 16 + (n-1)*8
I assume you can figure out whether it is A or B.
