Because the 2 lines are parallel, (5x+5) + 115 need to equal 180.
Solving for X:
5x+5 +115 = 180
5x + 120 = 180
Subtract 120 from each side:
5x = 60
Divide both sides by 5
x= 60/5
X = 12
Answer:
arithmetic
Step-by-step explanation:
The points fall on a straight line. They won't do that for a geometric sequence.
___
Normally the terms of either sort of sequence are numbered with counting numbers: 1, 2, 3, .... Your x-values are negative, so are obviously not term numbers of a sequence. The differences of x-values are 1, and the differences of y-values are 2.5, so we know the x- and y-values are linearly related. That relationship can be expressed in point-slope form by ...
y = 2.5(x +1) +12.5
which can be simplified to
y = 2.5x +15

The arithmetic sequence with first term 17.5 and common difference 2.5 would be described by this same equation.

I think you just subtract 59 and 11 but i could be wrong
