Find the wrong term in the following number series questions.
5,10,30,120,600,3000,25200

Options

A. A)10
B. B)600
C. C)30
D. D)3000

Answer

To find the wrong term in the series: 5, 10, 30, 120, 600, 3000, 25200, we will analyze the pattern of the series step by step.

### Step 1: Identify the Pattern
Let's look at how each term relates to the previous one:
- The first term is 5.
- The second term is 10, which is \(5 \times 2\).
- The third term is 30, which is \(10 \times 3\).
- The fourth term is 120, which is \(30 \times 4\).
- The fifth term is 600, which is \(120 \times 5\).
- The sixth term is 3000, which is \(600 \times 5\).
- The seventh term is 25200, which is \(3000 \times 8.4\) (not following the pattern).

### Step 2: Verify the Multiplication Pattern
Let's summarize the multipliers:
- \(5 \times 2 = 10\)
- \(10 \times 3 = 30\)
- \(30 \times 4 = 120\)
- \(120 \times 5 = 600\)
- \(600 \times 5 = 3000\) (this is where the pattern breaks)
- The next term should be \(600 \times 6 = 3600\), not 3000.

### Step 3: Identify the Incorrect Term
From the analysis, we see that after 600, the next term should have been \(600 \times 6 = 3600\). However, the term given is 3000, which does not follow the expected pattern.

Thus, the wrong term in the series is **3000**.

### Final Answer
The wrong term in the series is **3000**.
