Look at the following pattern:
`(9-1) // 8 = 1`
`(98-2) // 8 = 12`
`(987-3) // 8 = 123`
`(9876-4) // 8 = 1234`
According to this pattern, `(987654-6) // 8` is equal to:

Options

A. 123456
B. 12345
C. 1234
D. 123

Answer

To solve the problem, we will analyze the pattern given in the question step by step.

### Step 1: Understand the pattern
We observe the following calculations:
- `(9-1) // 8 = 1`
- `(98-2) // 8 = 12`
- `(987-3) // 8 = 123`
- `(9876-4) // 8 = 1234`

From these calculations, we can see that the left side consists of a number formed by consecutive digits starting from 9 down to 1, and the number being subtracted is the last digit of that number.

### Step 2: Identify the next term
Following the same pattern, we need to evaluate `(987654-6) // 8`.

### Step 3: Perform the subtraction
First, we calculate the subtraction:
- `987654 - 6 = 987648`

### Step 4: Perform the division
Next, we divide the result by 8:
- `987648 // 8`

### Step 5: Calculate the division
Now, we perform the division:
- `987648 ÷ 8 = 123456`

### Final Answer
Thus, according to the pattern, `(987654-6) // 8` is equal to `123456`.
