If the first and second digits in the sequence 5 9 8 1 3 2 7 4 3 8 are interchanged, also the third and fourth digits, the fifth and sixth digits and so on, which digit would be the seventh counting to your left?

Options

A. 1
B. 4
C. 7
D. 8

Explanation

To solve the problem step by step, we will follow the instructions given in the question regarding the interchanging of digits in the sequence.

### Step-by-Step Solution:

1. **Identify the Sequence**: The original sequence of digits is:
\[ 5, 9, 8, 1, 3, 2, 7, 4, 3, 8 \]

2. **Interchange the Digits**: We will interchange the digits as follows:
- First and second digits: 5 and 9
- Third and fourth digits: 8 and 1
- Fifth and sixth digits: 3 and 2
- Seventh and eighth digits: 7 and 4
- Ninth and tenth digits: 3 and 8

After performing these interchanges, the new sequence will be:
- First position: 9 (from 5)
- Second position: 5 (from 9)
- Third position: 1 (from 8)
- Fourth position: 8 (from 1)
- Fifth position: 2 (from 3)
- Sixth position: 3 (from 2)
- Seventh position: 4 (from 7)
- Eighth position: 7 (from 4)
- Ninth position: 8 (from 3)
- Tenth position: 3 (from 8)

Thus, the new sequence is:
\[ 9, 5, 1, 8, 2, 3, 4, 7, 8, 3 \]

3. **Count to Find the Seventh Digit from the Left**: Now, we need to find the seventh digit in the new sequence:
- 1st position: 9
- 2nd position: 5
- 3rd position: 1
- 4th position: 8
- 5th position: 2
- 6th position: 3
- 7th position: 4

Therefore, the seventh digit from the left is **4**.

### Final Answer:
The digit that would be the seventh counting from the left is **4**.
