Which sequence could be partially defined by the recursive formula f (n 1) = f(n) 2.5 for n ≥ 1? 2.5, 6.25, 15.625, 39.0625, … 2.5, 5, 10, 20 –10, –7.5, –5, –2.5, … –10, –25, 62.5, 156.25

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
