A video sharing website starts with 20,000 members. Each year it loses 25% of the members, but adds 10,000 new members after the reduction. Write a recursive rule to find the number of members for any year.
20,000 x 25 = 500,000 500,000 divided by 100 = 5,000 members are lost. Members left = 15,000 Members added = 10,000 Members every year = Members left + Members added = 15,000 + 10,000 = 25,000
