Hello, I have an answer to this question but my classmates have answered have all had different answers than me. I just want to make sure that I am correct.
Heres the question:
Andrew earns an allowance of $14 the first week, $17 the next week, $20 the following week, and so on.
How much will Andrew earn over the course of 10 weeks?
My answer--$42
My reasoning--Because the series increases by 3. Sooo 14+3=17+3=20+3=23+3=26 and so on until you add 3 to the number (n) 10 times. Which equals 42.
Am I right?
