<u>Step-by-Step </u><u>Explanation</u><u>:</u>
The given relation between the nth term and it's previous term is given by:

GiveN:
Now finding the other three terms of the AP with the given relation.

Putting a1 = 4,

Now, Third term:

Putting a2 = 8,

Now, Fourth term:

Putting a3 = 12,

130 (I have to write 20 character or more so I'm writing this)
<span>if a = 2x and b = 1
(2x)</span>³+1³ = (2x+1)(4x²-2x+1)
I hope this helps
