Bean sprouts grow very quickly. A bean sprout has grown to a height of 5 millimetrs. Tomorrow it will be 14 millimeters tall, the next day it will be 23 millimeters tall, and on the next day it will be 32 millimeters tall.
Part 1) Write a rule to represent the height of the bean sprout as an arithmetic sequence.

A(n) = 5 + (n - 1) 9
A(n) = 5 + (n - 1) 9
A(n) = 14 + (n - 1)9
A(n) = 14 + (n - 1)9
A(n) = 5 - (n - 1)9
A(n) = 5 - (n - 1)9
A(n) = 9n
A(n) = 9n
A(n) = 9 + (n + 1)5
Part 2) How tall will the bean sprout be in 12 days?
Part 1) The correct rule to represent the height of the bean sprout as an arithmetic sequence is:
A(n) = 5 + (n - 1)9
Part 2) To find the height of the bean sprout in 12 days, we can substitute n = 12 in the rule:
A(12) = 5 + (12 - 1)9 = 5 + 11 * 9 = 5 + 99 = 104
Therefore, the bean sprout will be 104 millimeters tall in 12 days.
