  5. Round 1 Question 3 Twice a number is three less than three times the number. What is the number?

  6. Round 1 Question 4 Use the sequence below: 18, 14, 10, 6 Write an explicit formula for the nth term.

  7. Round 1 Question 5 For a geometric sequence, you are given that a1 = 3 and r = 20. Find a4.

  8. Q1 answer: 51, 52, 53 Q2 answer: b = 20(4d) Q3 answer: 3 Q4 answer: an= -4n + 22 Q5 answer: 24,000 End of Round 1
