Each successive speed after the slowest is 10% greater than its predecessor. This suggests that the speeds form a geometric progression, not an arithmetic progression. The nth term in the geometric progression would be 2000(1.1^(n1))rpm, which you can evaluate for n = 5, 6 and 7 in order to answer part (a) of the problem.
