Question

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 days? A. A(n) = 16 + (n – 1)8; 104 inches B. A(n) = 16 + (n – 1)8; 116 inches C. A(n) = 16n; 192 inches D. A(n) = 12n; 144 inches

Answer 1

The answer is A. A(n) = 16 + (n-1)8; 104 inches.

n = day
2 = day 2

A(2) = 16 + (2-1)8
        = 16 + 8
        = 24 inches tall

i hope this helps
