#1**+2 **

This is for problem 1:

An easy way to determine if a sequence is geometric or arithmetic is by seeing if it is multiplied or divided by a number (geometric) or added or subtracted by a number (arithmetic).

A. The numbers in the sequence are divided by a number, the number being 2. This means it is geometric!

B. The numbers in the sequence have a number added to them, the number being 4. This means it is arithmetic!

#3**+2 **

This is for problem 2:

a. Plug in some values for \(f(x)=6x-4\)

1 | 2 |

2 | 8 |

3 | 14 |

4 | 20 |

This matches to 19.

b. If you are wondering how to solve this function, here's how:

Since you already know what f(1) is, you can start solving for f(2)!

\(f(2)=6 * f(2-1)= 6*f(1)= 6*2= 12\)

By doing this two more times, you can see this matches to 16.

c. Plug in some values for

1 | 2 |

2 | \(\frac{1}{3}\) |

3 | \(\frac{1}{18}\) |

4 | \(\frac{1}{108}\) |

You see this function matches to 18.

By this you can match d. to 17.

Matches:

16 ---> b.

17---> d.

18---> c.

19---> a.
