Show answer & explanation

Correct answer: C

To find the missing term in the sequence 3, 90, 3600, ___, 10800000, we need to determine the rule governing how each number changes to become the next.

Step-by-Step Analysis
Analyze the transitions:

3 to 90: 3 * 30 = 90

90 to 3600: 90 * 40 = 3600

Identify the pattern:

The multipliers are increasing by 10 each time (30, 40, ...).

Following this pattern, the next multiplier should be 50.

3600 * 50 = 180000.

Verify the final step:

If the pattern holds, the next multiplier should be 60.

180000 * 60 = 10800000.

The pattern is consistent.
