An arithmetic sequence is defined by the recursive formula t1 = 11, tn = tn - 1 - 13, where n ∈n and n > 1. which of these is the general term of the sequence? a) tn = 11 - 13(n - 1), where n ∈n and n > 1 b) tn = 11 - 13(n - 2), where n ∈n and n ≥ 1 c) tn = 11 - 13(n - 1), where n ∈n and n ≥ 1 d) tn = 11 - 13(n + 1), where n ∈n and n ≥ 1

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

answer: 40.95
