edgar is getting better at math. on his first quiz he scored 57 points then he scores 61 and 65 on his next two quizzes if his scores continued to increase at the same rate what will be his score on his 9th quiz?

While the geometric sequence is a sequence where each number after the first is identified by multiplying the previous one by a fixed number.
Given 57, 61, 65 the difference between the numbers is 4
