Answer:-4
Step-by-step explanation:
Well you see, you have 2/8, (fraction) and here is a few others,
These are COMMON. 4/16, 2/8, 6/24, etc....
You multiply the denominator and numerator by the same answer.
Thats how I think I learned it.
X=5 y=1 this what i got when i worked it out on my paper. hope that helps.
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.
