Answer: Finite
Step-by-step explanation
The set being described is
{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72}
There's a lot of numbers here so we can shorten the notation to
{2, 4, 6, 8, ..., 68, 70, 72}
The three dots mean "keep the pattern going". We stop the pattern once reaching 72 which is the largest even number that's just below 73.
This set is finite because the numbers do not go on forever. There's a fixed amount of them.
