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.
