is anyone recognizing this as an arithmetic series?

anonymous · Answer

Yes, the first post is incorrect

anonymous · Answer

It would be in the form of 110 + 20n, because with each installment the payment will increase an additional 20 dollars. There is a total of 6, so the sum of each installment needs to be added. So take the sum for each n up to 6
