  1. Which number in the sequence 8, 27, 64,100, 125, 216, 343 is wrongly written?
    1. 27
    2. 100
    3. 125
    4. 343
Correct Option: B

In the given sequence all the numbers except 100 are perfect cubes of natural numbers.
As, 8 = 2³,
27 = 3³,
64 = 4³
100 = 10² ≠ 10³
125 = 5³
Hence , the wrong term is 100.
