Given,
√2,3√2,5√2,7√2,........
A.P is known for Arithmetic Progression whose common difference = an – an-1 where n > 0

As,
a2 – a1 = a3 – a2 = a4 – a3
The given sequence is A.P Common difference,
d = a2 - a1 = 2√2
To find the next three more terms of A.P,
Firstly find an
We know,
an = a + (n-1) d where a is a first term or a1 and d is common difference

When n = 5 :

When n = 6 :

When n = 7 :
