An electrician earns $110 after his first hour of working for a client. his total pay based on the number of hours worked can be represented using the sequence shown. 110, 130, 150, 170, which recursive formula can be used to determine the total amount of money earned for each successive hour worked based on the amount of money currently earned?

He Starts: 110
First hour: 110 + 20: 130
Second hour: 130+20=150
Third hour: 150 + 20

Each hour he earns 20 USD
For total earn:
The ecuation may be: 110 + 20h.    h= worked hours.

When he starts, zero hour:   110 + (20)(0) = 110 + 0 = 110 USD
When he works one hour:   110 + (20)(1) = 110 + 20 = 130 USD
When he works two hours:   110 + (20)(2) = 110 + 40 = 150 USD
When he works three hours:   110 + (20)(3) = 110 + 60 = 170 USD

When he works five hours:   110 + (20)(5) = 110 + 100 = 210 USD

earns for sucesive worked hours.

Can be: 20h, where h = worked hours.

If he works one hour: 20 h = 20 x 1 = 20
If he works two hours: 20 h = 20 x 2 = 40
If he works three hours: 20 h = 20 x 3 = 60

I hope it can help you
