first term = initial number

second term = initial number + common difference

third term = initial number + 2(common difference)

So...

2x+5-(x+4) = common difference

4x+3-(2x+5) = also common difference

2x+5-(x+4) = x+1

4x+3-(2x+5) = 2x-2

Because x+1=2x-2 we can solve for x.

x=3

So the sequence goes... 7,11,15...

19 is the fourth term

Please help! Give the answer and how you got it
Ronch [10]

The distance between the points C(-3,1) and D(5,6) is 10.3 units.

<u>Step-by-step explanation:</u>

Let us consider CD is a line segment.

The point C is (-3,1) and D is (5,6).

The Cartesian formula for line is used to find the length between the CD.

Distance between two points = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.

The points are (-3,1) and (5,6).

=\sqrt{(6-(-3))^2+(6-1)^2}.

=\sqrt{(6+3)^2+(6-1)^2}

=\sqrt{9^2+5^2}.

=\sqrt{81+25}.

=\sqrt{106}.

=10.295 ≈ 10.3.

Distance between two points 10.3 units.
