12. Bamboo plants grow rapidly. A bamboo plant is 130 inches tall. Tomorrow it will be 143
inches tall, the next day it will be 156 inches tall, and on the next day it will be 169 inches tall.
Write a rule to represent the height of the bamboo plant as an arithmetic sequence. How tall
will the plant be in 12 days?
O A(n) = 130 + (n - 1)13; 273 inches
O A(n) = 130 + (n + 1)13; 299 inches
O A(n) = 13n; 156 inches
O A(n) = 12n; 144 inches

Answer 1

A(n) = 130 + (n-1)13; 273 inches

Explanation

by plugging in the number 12 in the equation we get 273, A(n)= 130+ (12-1)*13 = 273 By constantly subtracting backwards 13 from 273 we get the numbers we had before.
