Answer: 48, 29, 10, -9, -28

=====================================================

Step-by-step explanation:

The first term is 48 because of the notation f(1) = 48

To get the second term, we subtract 19 from 48

f(n) = previous - 19

f(2) = f(1) - 19

f(2) = 48 - 19

f(2) = 29

Then repeat the same idea for the third term

f(n) = previous - 19

f(3) = f(2) - 19

f(3) = 29- 19

f(3) = 10

The process keeps going until you have five terms as listed in bold above.

It is an arithmetic sequence with first term 48 and common difference -19.
