If Jim works at Fire Fighting Equipment, has $32,874 in sales in one week, and as paid a weekly salary of $452 plus a commission
of .9% on sales between $15,000 and $25,000, with 1.1% paid on sales in excess of $25,000, no commission is paid on the first $15,000, what is his gross earning?
From the explicit formula: an=3+(n-1)8 simplifying this we get: an=3+8n-8 an=8n-5 thus the recursive formula is: an=an-1+ the missing part is the common difference which is 8
