Answer 2

Given,

An Arithmetic Progression -10,-6,-2,2.

To find,

The common difference of the AP -10,-6,-2,2.

Solution,

• Arithmetic Progression is defined as terms that follow a proper sequence and have a common difference between their terms.

• If the terms a1, a2, a3, a4 are in Arithmetic Progression then the common difference (d) is calculated as a2-a1, a3-a3, a4-a3.

Similarly, the common difference in terms -10,-6,-2,2 would be calculated as-

⇒   -6 - (-10) = -6 + 10 = 4

⇒   -2 -(-6) = -2 + 6 = 4.

Hence, We can see that the common difference in the  AP -10,-6,-2,2, is  4.
