Answer:
3
Step-by-step explanation:
Each term of the sequence has 0.5 added to the one before. The first 10 terms are ...
-1.5, -1.0, -0.5, 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0
f(10) = 3.0
_____
If you like, you can use the given information about the first term (-1.5) and the common difference (0.5) to write an explicit formula:
f(n) = f(1) +d(n -1)
f(n) = -1.5 +0.5(n -1)
Then the 10th term is ...
f(10) = -1.5 +0.5(10 -1) = -1.5 +4.5 = 3
