Andrea manages a company that currently has 116 customers, which is 8 more than twice the number of customers the company had 1 year ago. how many customers did the company have 1 year ago?

Company had 54 costumers 1 year ago.

Step-by-step explanation:

Let x be the number of company's customers 1 year ago,

Since, currently, the customers are 8 more than twice the number of customers the company had 1 year ago,

So, the current number of costumers = 2x + 8,

According to the question,

2x + 8 = 116

Subtract 8 on both sides,

2x = 108

Divide both sides by 2

x = 54

Hence, company had 54 costumers 1 year ago.

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
