Final answer:
To find the total number of students who participated in the afforestation program where each student planted plants equal to their own number, an equation is set up and solved based on the given information.
Explanation:
To determine the number of students who took part in the afforestation program, we can set up an equation based on the information provided. Let x represent the number of students. Each student planted a number of plants equal to their own number, so the total number of plants planted is the sum of the students' numbers: x + (x-1) + (x-2) + ... + 1. This sum represents the total planted, which is 4225. By solving this equation, we can find the number of students who participated.
