Levi has 3 marbles. Each week his friend adds 30 more marbles to his collection. Which explicit formula shows the number of marbles he will have after n number of weeks?

• a_n = 3 - 30(n -1)

• a_n = 3 + 30(n -1)

• a_n = 30 - 3(n -1)

• a_n = 30 + 3(n -1)

Write the recursive formula for 6, 17, 28, 39, 50....

• a_n=a_n-1+11
  a₁=6
• a_n=a_n-1-4
  a₁=6
• a_n=a_n-1+9
  a₁=6
• a_n=a_n-1+6
  a₁=6
