Bobs hardware sells buckets in five different sizes. The tiny bucket holds 5 quarts, the small holds 10 quarts, the medium holds 20 quarts, and the large holds 40 quarts. How many quarts will the extra-large bucket hold?

80

Step-by-step explanation:

you have to guess the pattern and it seems like each bucket's size is twice the previous one

tiny = 5

small = 10 (tiny * 2)

medium = 20 (small * 2)

large = 40 (medium * 2)

extra-large = 80 (large * 2)
