To solve this you need to take the answer from the previous iteration.

Iteration 1: The answer is given
a1 = 300

Iteration 2: Solve using the equation. a(n-1) is the answer from the previous iteration. n = the number of the current iteration. So, a(n-1) = 300 and n = 2

a2 = 300/2 = 150

Iteration 3: a(n-1) = 150 and n = 3
a3 = 150/3 = 50

Iteration 4: a(n-1) = 50 and n = 4
a4 = 50/4 = 12.5

Answer: 12.5
