Question

the commen difference of AP 4,-2,0,4​

Answer 1

$\huge\underline{\underline{\red{\textbf{Explanation : -}}}}$

To find :

• common difference of AP

Solution :

• AP :- 4 , -2 , 0 , 4 ....

Common difference = second term - first term

Or, third term - second term and so on we can did this process.

First term = 4

Second term = -2

Third term = 0

• Common difference :

⠀⠀⠀⠀⠀›› a2 - a1

⠀⠀⠀⠀⠀›› -2 - 4

⠀⠀⠀⠀⠀›› - 6

Or

⠀⠀⠀⠀⠀›› a3 - a2

⠀⠀⠀⠀⠀›› 0 - 2

⠀⠀⠀⠀⠀›› -2

Or

⠀⠀⠀⠀⠀›› a4 - a3

⠀⠀⠀⠀⠀›› 4 - 0

⠀⠀⠀⠀⠀›› 4

So, common difference is not same so given series is not an AP.
