Finding the Missing Number in the Series

We need to find the next number in the series:

\[ 3,\ 6,\ 12,\ 24,\ ? \]

Understanding the Pattern

Let us look at how each number is related to the previous one.

  • \(3 \times 2 = 6\)
  • \(6 \times 2 = 12\)
  • \(12 \times 2 = 24\)

So, each number is obtained by multiplying the previous number by \(2\).

Step-by-Step Solution

Step 1: Identify the rule.

The pattern is:

\[ \text{Next term} = \text{Previous term} \times 2 \]

Step 2: Apply the rule to the last given term.

The last number is \(24\).

\[ 24 \times 2 = 48 \]

Final Answer

The missing number is \(48\).

Summary

  • Given series: \(3, 6, 12, 24, ?\)
  • Pattern used: multiply by \(2\)
  • Missing number: \(48\)
