What should come in place of the question mark (?) in the given series?
499, 498, 490, 463, 399, ?

The correct option is 274.

To find the missing number in the given series, let us analyze the difference between consecutive terms:

$499-498=1$

$498-490=8$

$490-463=27$

$463-399=64$

Observing the pattern of the differences (1, 8, 27, 64), we can see that they are cubes of consecutive natural numbers:

$1^3=1$
$2^3=8$
$3^3=27$
$4^3=64$

Following this pattern, the next difference must be the cube of 5:

$5^3=125$

Now, subtract 125 from the last term (399) to find the missing number:

$399-125=274$

Hence, the number that comes in place of the question mark (?) is 274.
