State if this sequence is Arithmetic, Geometric, or neither

1.)Geometric

2.)Arithmetic

3.)Arithmetic

4.)Arithmetic

5.)Geometric

Step-by-step explanation:

Geometric is here you multiply  or divide the same number to different numbers to get a sequence. Arithmetic is where you ad or subtract.

The given values of abscissa and ordinate in the given are that which when substituted to the values of x and y in the equation will make the equation true. This means that the left and right-hand side of the equation will be equal. The established equations should have a basis of,

        x + y = c

The equations are,

    x + y = 6

Substituting x = 7 and y = -1,

    7 + (-1) = 6 ; 6 = 6

 The other two equations will be,

    2x + y = 13  and,

    x + 2y = 5

 It is to be noted that countless of equations can be made with the given solution so long as the equation is valid.
