Study the pattern :
`{:(1xx8+1=9,1234xx8+4=9876),(12xx8+2=98,12345xx8+5=98765),(123xx8+3=987,):}`
Write the next two steps. Can you say how the pattern works?

Answer

To solve the problem, we will analyze the given pattern and find the next two steps.

### Step-by-Step Solution:

1. **Identify the Pattern**:
- The first part of each equation consists of a sequence of numbers multiplied by 8.
- The second part is a number added to the product of the multiplication.
- The result is a decreasing sequence of digits starting from 9.

2. **Write the first two steps based on the pattern**:
- The first step is `1 x 8 + 1 = 9`
- The second step is `12 x 8 + 2 = 98`
- The third step is `123 x 8 + 3 = 987`
- The fourth step is `1234 x 8 + 4 = 9876`
- The fifth step is `12345 x 8 + 5 = 98765`

3. **Continuing the Pattern**:
- For the sixth step, we take `123456 x 8 + 6`.
- Calculation:
- \( 123456 \times 8 = 987648 \)
- \( 987648 + 6 = 987654 \)
- Therefore, the sixth step is `123456 x 8 + 6 = 987654`.

4. **Next Step**:
- For the seventh step, we take `1234567 x 8 + 7`.
- Calculation:
- \( 1234567 \times 8 = 9876544 \)
- \( 9876544 + 7 = 9876551 \)
- Therefore, the seventh step is `1234567 x 8 + 7 = 9876551`.

### Final Answer:
The next two steps in the pattern are:
- \( 123456 \times 8 + 6 = 987654 \)
- \( 1234567 \times 8 + 7 = 9876551 \)
