If 2 = 0, 3 = 3, 4 = 6, 5 = 9 then 7 = ?

Options

A. 18
B. 12
C. 15
D. 16

Explanation

To solve the problem step by step, let's analyze the given relationships:

1. **Identify the pattern**:
We are given a sequence where:
- 2 = 0
- 3 = 3
- 4 = 6
- 5 = 9

2. **Observe the differences**:
- From 2 to 3, the output increases from 0 to 3 (difference of 3).
- From 3 to 4, the output increases from 3 to 6 (difference of 3).
- From 4 to 5, the output increases from 6 to 9 (difference of 3).

3. **Establish the next term**:
- The pattern shows that each time we move to the next integer, we add 3 to the previous output.
- Therefore, for 6, we would have:
- 5 = 9, so for 6, we add 3:
- 9 + 3 = 12.

4. **Calculate for 7**:
- Now, we apply the same logic to find the value for 7:
- 6 = 12, so for 7, we add 3 again:
- 12 + 3 = 15.

5. **Conclusion**:
- Thus, 7 = 15.

**Final Answer**: 7 = 15.
