Answer 2

Given: The given series is 9, 21, 45, 93,? 381.

To find: We have to find the missing term.

Solution:

The missing term in the series can be determined as follows-

The given series is 9, 21, 45, 93,? 381.

Let the missing term be x.

The series follows a specific pattern.

The pattern is as follows-

$9 \times 2 + 3 = 21 \\ 21 \times 2 + 3 = 45 \\ 45 \times 2 + 3 = 93$

Thus, the next term will be given as the double of 93 added by 3.

The value of x is as follows-

$93 \times 2 + 3 = 189$

Thus, the next term is 189.

The missing term is 189.
