Best answer
Correct Answer - Option 3 : 217

The given series are -

3, 28, 4, 65, 5, 126, 6, ?

Cube of the first number and add one then we get second number-

33 + 1 = 27 + 1 = 28

Cube of the third number and add one then we get fourth number-

43 + 1 = 64 + 1 = 65

Cube of the fifth number and add one then we get sixth number-

53 + 1 = 125 + 1 = 126

Similarly,

Cube of the seventh number and add one then we get eight number-

63 + 1 = 216 + 1 = 217

Hence, "217" is the correct answer.
