Fill in the blanks to complete the sequence: If the first two terms of an arithmetic sequence are 2 and 4 what would the next two numbers be? Sequence: 2, 4, ______ , ______

• 8, 16

• 6, 8

• 16, 256

• 2, 4

Answer explanation

Arithmetic sequence means a sequence where you ADD the same thing over and over. AKA linear sequence

Write the explicit rule for this tile pattern.

• f(n)= 2n + 3

• f(n) = 3n + 2

• f(n) = 3n + 3

• f(n) = 2n + 2

Write the recursive rule for this tile pattern.

• next=previous + 2

• previous = next + 2

• next = 2(previous)

• y=2x+3

Write a recursive formula for the following sequence: 10, 5, 0, -5,...

• a₁= 10

  a_n= a_n-1 - 5

• a₁= 10

  a_n= a_n-1 + 5

• a₁= 10

  a_n= a_n (5)

• a₁= 10

  a_n= a_n-1 (5)
