Answer:

  • 8, 20, 32, 44, 56
  • arithmetic

Step-by-step explanation:

The words "common difference" tell you this is an arithmetic sequence. A geometric sequence will have a <em>common ratio</em> between terms.

__

The common difference is added to each term to get the next.

  first term: 8 -- given

  second term: first term + common difference = 8 + 12 = 20

  third term: 20 +12 = 32

  fourth term: 32 +12 = 44

  fifth term: 44 +12 = 56

The first 5 terms of this arithmetic sequence are 8, 20, 32, 44, 56.

Solve for x <br> 6x+3y=54<br> 2x+y=18
butalik [34]

Step-by-step explanation:

6x+3y=54

- 2x+y=18

I'm going to be using the elimination method cause it seems easiest here. so for the elimination method u choose a variable to eliminate I chose y u could do x too if u want to. so first step would be to multiply the second equation by 3. 6x+3y=54

so now u just have to eliminate

6x+3y=54

- 6x+3y=54

because these cancel out the answer would be an infinite solution
