Final Answer:

The third term in the sequence defined by the recursive rule f(n) = f(n-1)/2 +5 is 8.5.

Step-by-step explanation:

Given recursive rule:

f(n) = (f(n-1)/2) + 5

Given first term:

f(1) = 4

Using the recursive rule to find f(2):

f(2) = (f(1)/2) + 5

f(2) = (4/2) + 5

f(2) = 2 + 5

f(2) = 7

Using the recursive rule again to find f(3):

f(3) = (f(2)/2) + 5

f(3) = (7/2) + 5

f(3) = (7 + 10)/2

f(3) = 17/2

f(3) = 8.5

Therefore, the third term (f(3)) in the sequence is 8.5.
