Question

If given the following AP what is the common difference 10, 15, 20

Answer 1

Answer:

The common difference of the given AP is d=5.

Step-by-step explanation:

Given the sequence

$10,\:15,\:20$

An Arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

Computing the common difference of all the adjacent terms

$10,\:15,\:20$

$15-10=5,\:\quad \:20-15=5$

As the difference between all the adjacent terms is the same and equal to

$d=5$

Therefore, the common difference of the given AP is d=5.
