If i’m understanding this correctly, your equation would be 2(n-1) -1. n being the first number you are plugging in, which begins with 10.
10, 17, 31, 59, 115

Midpoint Formula:

Sedaia [141]

The coordinates of the midpoint of the segment joining the two points (0, 2) and (6, 4) is (3, 3)

<h3>Solution:</h3>

Given that two points are (0, 2) and (6, 4)

To find: coordinates of the midpoint of the segment joining the two points

The midpoint of line joining two points is given as:

For a line containing two points $(x_1, y_1)$ and $(x_2, y_2)$

$\text {Midpoint}(x, y)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$

In the given sum, two points are (0, 2) and (6, 4)

$x_{1}=0 ; y_{1}=2 ; x_{2}=6 ; y_{2}=4$

Substituting the values in given formula,

$\begin{array}{l}{\text {Midpoint}(x, y)=\left(\frac{0+6}{2}, \frac{2+4}{2}\right)} \\\\ {\text {Midpoint }(x, y)=\left(\frac{6}{2}, \frac{6}{2}\right)=(3,3)}\end{array}$

Thus the required midpoint is (3, 3)
