I think that using the elimination method is the best, because it is the only method that I use when solving these types of equation. For example, for these two equations, you need to multiply one of the equations by a certain number so that you'd be able to find x and y. The elimination method is the method that tells you to do that. It is also the easiest method.

~Hope I helped!~

Determine whether the sequence appears to be an arithmetic sequence. If so, find the common difference and the next three terms
guapka [62]

an aritmetic sequence increases by the same amount each time (if it decreases, then it increases by a negative number)


the common difference is the number that must be added to a term to get the next term


let's see if it increases by the same amount

-5 to -11 is increase of -6

-11 to -17 is increase of -6

-17 to -23 is increase of -6

-23 to -29 is increase of -6


so it appears to be aritmetic

common difference is -6

-29-6=-35

-35-6=-41

-41-6=-47

the next 3 terms are -35, -41, -47
