Correct Answer - Option 3 : 2063
Calculation:
A perfect square near a natural number can be done by the hit and trial method unless it is a large number with more than 4 digits.
⇒ Original sequence : 1, 2, 3, 4, 5, 6, ......
⇒ New sequence : 2, 3, 5, 6, 7, 8, 10, ........
⇒ Thus before 2018, there are 44 perfect squares (442 = 1936).
⇒ Thus 44 numbers will be missing in the new sequence compared to the original, thus the 2018th number will be 2018 + 44 = 2062.
⇒ Students often tend to mistake here by ticking 2062.
⇒ [452 = 2025] will be included in the new sequence too, thus 2062 + 1 = 2063 is the correct answer.
