Answer:
aₙ = 31n - 5
Step-by-step explanation:
The terms of your sequence are.
26, 57, 88, …
This is an arithmetic sequence, because there is a constant difference of 31 between consecutive terms.
The explicit formula for the nth term of an arithmetic sequence is
aₙ = a₁ + d(n - 1 )
a₁ is the first term, and d is the difference in value between consecutive terms. Thus,
aₙ = 26 + 31(n - 1) = 26 + 31n - 31
aₙ = 31n - 5
The explicit rule for the arithmetic sequence is aₙ = 31n - 5.
The answer is B. $18.00 X 0.30=$5.40 you then subtract the 5.40 from 18.00, 18.00-5.40 =$12.60, you then multiply $12.60 x 0.08= 1.01 rounded, then you add 12.60 = 1.01 = $13.61
