1) Write the explicit rule so that you can find any term in the series without finding the previous terms first. How many phones will be sold during week 37?

 

2) The payroll department wants to know how many sales they can expect during the first year of the campaign. Assume there are 52 weeks in a year. How many phones will be sold total during the entire first year? Write and evaluate the expression for the correct partial sum of the series.

1)   Explicit  

 

Number sold in any week, n  =   510(1.12)^(n - 1)

 

2)  Total phones sold in first year

 

510 [ 1 - 1.12^52 ] / [ 1 - 1.12 ] ≈ 1,536,478
