A new fitness center opened up with 24 clients. Each week they are signing up an average of 5 new members. The business owner wrote the explicit formula for this situation as being A(n) = 24 + (n  1)(5). Is this correct for this situation? Justify your answer using complete sentences and proper grammar.

Best ResponseYou've already chosen the best response.0so i think no .. They start with 24. And get 5 a week. I am assuming the n stands for the week. A=24 + 5(n) am i right ?

Best ResponseYou've already chosen the best response.1it depends on what we count as week 1. Normally people count week 1 as the starting point (where A = 24) so you would want the formula in the question A= 24 + (n1)*5

Best ResponseYou've already chosen the best response.1Your equation A(n)= 24+5n means you start counting at n=0 we could do that, but (unfortunately) the people who wrote this question assume we start at n=1. They assume that, because that is how sequences are often taught, and they don't expect the student to think too much about it.

Best ResponseYou've already chosen the best response.0but why would n 1 ?

Best ResponseYou've already chosen the best response.1you want A(1) to be 24 if you use A(n)= 24+5*n we would get A(1)= 24+5*1 = 29 (i.e. 5 too many) to fix it up, we first subtract 1 from n. now it will work A(1)= 24 A(2)= 29 (5 more) A(3)= 34 , etc

Best ResponseYou've already chosen the best response.1The formula tells you how to figure out how many members there will be, depending on the week. We start with week 1 , with 24 members
