\dfrac{25}{8}\left(\dfrac{8}{5}\right)^1=5\\\\\dfrac{25}{8}\left(\dfrac{8}{5}\right)^2=5\cdot\dfrac{8}{5}=8\\\\\dfrac{25}{8}\left(\dfrac{8}{5}\right)^3=8\cdot\dfrac{8}{5}=12.8\\\\\dfrac{25}{8}\left(\dfrac{8}{5}\right)^4=12.8\cdot\dfrac{8}{5}=20.48

The explicit form:

a_n=\dfrac{25}{8}\left(\dfrac{8}{5}\right)^n

The recursive form:

a_n=\left\{\begin{array}{ccc}a_1=5\\a_{n+1}=\dfrac{8}{5}a_n\end{array}\right

How do you draw a skew line?
Bas_tet [7]
In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of lines through opposite edges of a regular tetrahedron. Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions. Two lines are skew if and only if they are not coplanar. Hope this helps!! :)
