Respuesta :

Yearly attendance = 56,000
The growth rate is 4.2% or 0.042 per year.

That is,
Year 0: 56,000
Year 1: 56,000*1.042
Year 2: 56,000*1.042²

and so on.

This is a geometric sequence with
a₁ = 56,000 and r = 1.042

The n-th term is 
a(n) = a₁ rⁿ⁻¹

When n=9, obain
a₉ = 56,000*1.042⁸ = 77,826.9 ≈ 77,827

Answer: 77,827
