Question

Bamboo plants grow rapidly. A bamboo plant is 140 inches tall. Tomorrow it will be 154 inches tall, the next day it will be 168 inches tall, and on the next day it will be 182 inches tall. Write a rule to represent the height of the bamboo plant as an arithmetic sequence. How tall will the plant be in 16 days?

Answer 1

350 inches

Explanation:

aₙ = a₀ + d(n-1)

d = common difference

a(16 days) = 140 + 14(15)

= 140 + 210

= 350
