?2. A jump-rope manufacturer has invited 128 teams to participate in a rope-jumping contest. Teams are paired, and any team that loses one match is eliminated from the contest. How many matches are needed to determine the winner?......
What is the eighth number in the pattern:
1. 5; 25; 125; 625; 3,125; 15,625; . . . ? (1 point)

For the first question it's the multiple of 5, so you would multiply each term by 5 to get the next term.

So 15,625 times 5 is equal to 78,125.


For the second you question, keep dividing the number by 4.(Two teams, each have two people so that's 4)

So you would get 128/4 is 32 (That's one match). 32/4 is 8 (That's 2 matches). 8/4 is 2 (That's three matches and that's is your winner).


So for the second question the answer is 3 matches.
