Express the series into a summation notation

Juan’s father is giving him an allowance of ₱150 every day for 7 days. His father decided to increase the amount given each day as a reward for being an honor student. If Juan’s father will increase Juan’s allowance by ₱50 each day, how much will Juan receive?

Perhaps you misread the problem. The series would be 150 + (150 + 50) + (150 + 2(50)) + ... + (150 + 7(50)).

Perhaps. I did not read it like that. Although I did consider it. If that is the case then it could be sum from 1 to 7 of (150 + 50(n-1)) or a variation of that depending if you include the 50 on the first day.
