The number of apples eaten on the first day can be calculated by working backwards from the total number of apples eaten over 5 days.

• Calculate the total number of apples eaten over 5 days: 100 apples

• Subtract the apples eaten on the 2nd day (6 more than the 1st day), 3rd day (6 more than the 2nd day), and so on until the 5th day to find the apples eaten on the 1st day

• Example: 1st day = x, 2nd day = x + 6, 3rd day = x + 12, 4th day = x + 18, 5th day = x + 24. Total = 100 apples
