Answer:
The ratio is 1:3
Step-by-step explanation:
Let
x -----> the number of tables in the restaurant
y ----> the number of chairs in the restaurant
we know that
To find out the ratio of tables to chairs in the restaurant, divide the number of tables by the number of chairs
we have

so
The ratio is equal to

Simplify
Divide by 18 both numerator and denominator

therefore
The ratio is 1:3
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.
