MCQ

The sequence $\frac{5}{{\sqrt 7 }}$, $\frac{6}{{\sqrt 7 }}$, $\sqrt 7 $, ....... is

A
$H.P.$
B
$G.P.$
✓
$A.P.$
D
None of these

✓

Answer

Correct option: C.

$A.P.$

c
(c) Common difference is $d = \frac{6}{{\sqrt 7 }} - \frac{5}{{\sqrt 7 }} = \frac{1}{{\sqrt 7 }} = \sqrt 7 - \frac{6}{{\sqrt 7 }}$.

Hence given sequence is $A.P.$
