A new night club opens. The first night 100 patrons attend. For each successive night for a month, 20 more attend. How many attend on the 7th night?

Arithmetic sequence formula finding the nth number:

an = a1 + (n – 1)d

A(7) = 100 + (7-1) 20

A(7) = 100 + (6)20

A(7) = 100 + 120

A(7) = 220


So, on the 7th night, there 220 patrons.
