Solution:
The logic follows here is :
Square of 3rd term × 3 = 1st term,
Square of 3rd term × 2 = 2nd term,
(243, 162, 9) → (92×3=243), (92×2=162)
1). (100, 50, 5) → (52×3≠100), (52×2=50)
2). (278, 78, 8) → (82×3≠278) , (82×2≠78)
3). (48, 32, 4) → (42×3=48), (42×2=32)
4). (225, 25, 5) → (52×3≠225), (52×2≠25)
Hence, the correct answer is "(48, 32, 4)".
