Question

Common difference of the AP - 8 - 5 - 2 1........ Is

Answer 1

Answer:

common different = a2 - a1

Step-by-step explanation:

= -5 -(-8) = -5+8 =3. so the common difference = 3

Answer 2

Given:

AP: - 8, -5, -2, 1

To Find:

Common Difference

Solution:

Here, we have the following AP :

-8, -5, -2, 1  ; where

$a_{1} = -8$

$a_{2} = -5$

We know that,

Common Difference = $a_{2} - a_{1}$

By substituting the values of $a_{1}$ and $a_{2}$ in the equation above, we get

Common Difference = -5 - ( -8 )

                                  = -5 + 8

                                  = 3

Hence, the common difference of the given AP is 3.
