Question

common difference of ap root 7,root 28,root63

Answer 1

hey dude!
root 7,root28,root63
a=root7 root 28 we can write =2root7
d=2root7-root7
=root7 (2-1)
= root 7 ans
plz marks as brainlist

Answer 2

Answer:

The common difference is $d=\sqrt{7}$

Step-by-step explanation:

Given : The AP series $\sqrt{7} ,\sqrt{28} , \sqrt{63}$

To find : The common difference of the AP series?

Solution :

In the AP series the common difference is the second term- first term

$d=a_2-a_1$

Where, d is the common difference

$a_1=\sqrt{7} , a_2=\sqrt{28}$

$d=\sqrt{28}-\sqrt{7}$

$d=2\sqrt{7}-\sqrt{7}$

$d=\sqrt{7}(2-1)$

$d=\sqrt{7}$

Therefore, The common difference is $d=\sqrt{7}$
