Write a sequence that models the situation. explain how you know if this sequence is arithmetic or geometric?

The sequence is geometric because we multiply by the same number each time to get the next term. In this case, we multiply by 1/2 = 0.5 to get the next term.

first term = 64

second term = 0.5*(first term) = 0.5*64 = 32

third term = 0.5*(second term) = 0.5*32 = 16

fourth term = 0.5*(third term) = 0.5*16 = 8

and so on

The sequence of values would be

64, 32, 16, 8, 4, 2, 1

Since we're talking about a number of teams, it doesn't make sense to keep going after 1 (since we can't have half a team).
