Answer:
Arithmetic sequence formula is: \(a_n = 20 + (n - 1) \times 4\)
After 9 customers there are 52 tires in the bin
Step-by-step explanation:
The general arithmetic sequence formula is:
\(a_n = a_1 + (n - 1) \times d\)
where \(a_1\) is the first term, \(a_n\) is the nth term, n is the term position and d is the common difference.
Assuming \(a_1\) = 20
The second term is 24, then:
\(24 = 20 + (2 - 1) \times d\)
d = 24 - 20 = 4
So, for this case, the arithmetic sequence formula is:
\(a_n = 20 + (n - 1) \times 4\)
With n = 9:
\(a_9 = 20 + (9 - 1) \times 4\)
\(a_9 = 52\)
