We are given the following sequence:
The formula that we can use to obtain the sequence is the following:
Because when we replace the given terms we get:
For the next term:
It is not because it is a whole number fractions are mixed numbers
Distance from a point to a line (Coordinate Geometry)
Method 1: When the line is vertical or horizontal
, the distance from a point to a vertical or horizontal line can be found by the simple difference of coordinates
. Finding the distance from a point to a line is easy if the line is vertical or horizontal. We simply find the difference between the appropriate coordinates of the point and the line. In fact, for vertical lines, this is the only way to do it, since the other methods require the slope of the line, which is undefined for evrtical lines.
Method 2: (If you're looking for an equation) Distance = | Px - Lx |
Hope this helps!
The answer is
D.(n+3)!
We just need to simplify the expression
(n+4)!/(n+4) =(n+3)! * (n+4)/(n+4)
(n+4)!/(n+4) = (n+3)! * 1
(n+4)!/(n+4) = (n+3)!
