# Using the arithmetic sequence of numbers 1,3,5,7,9..., what is d, the difference between any 2 terms?

color(blue)(d=2

#### Explanation:

The sequence is
$1 , 3 , 5 , 7 , 9$

The common difference $d$ is the difference between any two consecutive numbers of the series.
${d}_{1} = 3 - 1 = 2$

${d}_{2} = 5 - 3 = 2$

${d}_{3} = 7 - 5 = 2$

So the common difference $d$ of this arithmetic sequence:
color(blue)(d=2
