The inequality expression for the number of years when tree will be atleast 20 feets tall is x ≥14

Current height = 2

Growth rate = 1.3 feets per year

The height of the tree after x years can be represented as a linear equation thus :

Height = 2 + 1.3x

Number of years when the tree will be 20 feets tall :

20 = 2 + 1.3x
20 - 2 = 1.3x
1.3x = 18
x = 13.84

The tree would be atleast 20 feets tall in 14 years x this can be expressed thus

x ≥14

Answer:

a. Arithmetic

b. $a_{n} = a_{n-1} + 15$

c. $a_{n} = 15n + 125$

Step-by-step explanation:

A sequence is arithmetic when the difference between one term and the next is a constant. On the other hand, a sequence is geometric when the next term is found by multiplying the previous by a constant.

In this case, the next term of the sequence can be found by adding $15. Therefore, the sequence is ARITHMETIC ✔️

The recursive formula will be the following: $a_{n} = a_{n-1} + 15$

The explicit formula is the following: $a_{n} = 15n + 125$
