This problem describes an arithmetic sequence where the number of oranges received by each boy decreases by a constant amount. Let N be the number of boys. Let a_1 be the number of oranges the oldest boy receives. Let d be the constant difference in the number of oranges. Since each boy receives a constant number of oranges more than the next student (implying the sequence is decreasing from oldest to youngest), the common difference of the sequence a_1, a_2, , a_N will be -d, where d is a positive integer. Step 1: Set up the given information. The oldest boy receives 7 oranges, so the first term is $a_
