The first time Myra competed in a 500 meter free style race, her time was 15 minutes flat. Each subsequent race, Myra’s race was reduced by 10 seconds

Question

Complete the statement
The context is best represented by __________(an arithmetic sequence, a linear function) and the domain is ______(continuous, or discrete).

Answer 1

The context is best represented by an arithmetic sequence and the domain is discrete.

In this situation, Myra's race times decrease by a fixed amount (10 seconds) for each subsequent race, which characterizes an arithmetic sequence. The domain is discrete because the number of races is countable (1st race, 2nd race, etc.).
