Answer:

n^2 + 3.

Step-by-step explanation:

4 7 12 19

Differences are 3 5 7 so this a quadratic sequence.

2nd difference = 2 2

So the first part of the expression is n^2

Terms: 4 7 12 19

n^2 1 4 9 16

Difference = 3 3 3 3 3

So the answer is n^2 + 3.

The endpoints of GH are G(3,3) and H(-7,7). Find the coordinates of the midpoint M.

sesenic [268]

Step-by-step explanation:

Hey there!!

You can simply use midpoint formulae to find midpoint of the coordinates.

Here, Given that;

G(3,3) and H(-7,7).

Using midpoint formulae,

$midpoint \: of \: gh = (\frac{x1 + x2}{2} ,\frac{y1 + y2}{2}$ )

$midpoint \: of \: gh = (\frac{3 - 7}{2} ,\frac{3 + 7}{2}$ )

After simplifying it we get,

= (-2,5).

Therefore, midpoint of GH is M(-2,5).

Hope it helps....
