Solution:The pattern followed here is :Add + 2 to all the numbers to get a perfect cube.
(510, 727, 1329) → {(510 + 2), (727 + 2), (1329 + 2)} ⇒ (512, 729, 1331) ⇒  (8³, 9³, 11³ )
(1726, 2195, 3373) → {(1726 + 2), (2195 + 2), (3373 + 2)} ⇒ (1728, 2197, 3375) ⇒ (12³, 13³, 15³ )
Similarly,
(1726, 998, 341) → {(1726 + 2), (998 + 2), (341 + 2)} ⇒ (1728, 1000, 343) ⇒ (12³, 10³, 7³ )
Hence, "(1726, 998, 341)" is the correct answer.
