Detailed Solution & Explanation

We are given the series: 3,10,29,66,127,…\displaystyle 3, 10, 29, 66, 127, \dots
Let's express each term in relation to perfect cubes:
- 3=13+2\displaystyle 3 = 1^3 + 2
- 10=23+2\displaystyle 10 = 2^3 + 2
- 29=33+2\displaystyle 29 = 3^3 + 2
- 66=43+2\displaystyle 66 = 4^3 + 2
- 127=53+2\displaystyle 127 = 5^3 + 2
The series is of the form n3+2\displaystyle n^3 + 2 for consecutive natural numbers n\displaystyle n.
The next term must be 63+2\displaystyle 6^3 + 2:
63+2=216+2=2186^3 + 2 = 216 + 2 = 218
Hence, **Option D** is the correct answer.
