Answer: 300 students were members of the health club during the month of october.

Step-by-step explanation:

Let x represent the number of students that were members of the health club during the month of october.

Let x represent the number of other members of the health club during the month of october.

The health club had a total of 900 members during the month of October. This means that

x + y = 900

The health clubs membership fee is $10 per month for students and $25 per month for all other members. They received a total of $18,000 in October. This means that

10x + 25y = 18000 - - - - - - - - - - -1

Substituting x = 900 - y into equation 1, it becomes

10(900 - y) + 25y = 18000

9000 - 10y + 25y = 18000

- 10y + 25y = 18000 - 9000

15y = 9000

y = 9000/15

y = 600

x = 900 - y = 900 - 600

x = 300

Step-by-step explanation:

<u>Given recursive formula</u>

  • a₁ = 0
  • aₙ = 2(aₙ₋₁)² - 1, for n>1​

<u>The first 5 terms are:</u>

  • a₁ = 0
  • a₂ = 2(0)² - 1 = 0 - 1 = -1
  • a₃ = 2(-1)² - 1 = 2 - 1 = 1
  • a₄ = 2(1)² - 1 = 2 - 1 = 1
  • a₅ = 2(1)² - 1 = 2 - 1 = 1
