# How do you graph the arithmetic sequence a_n=5-2n?

Mar 17, 2018

As below.

#### Explanation:

$y = m x + c$ is the standard form of slope equation of a line.

Given ${a}_{n} = - 2 n + 5$

Slope of the line $m = - 2$, y-intercept $= 5$

${a}_{1} = - 2 + 5 = 3$

${a}_{2} = 5 - 4 = 1$

a_3 = 5 - 6 = -1#

${a}_{1} = 5 , d = - 2$
