Explanation

To solve the problem of correctly reporting the answer of the addition of 154.21, 6.142, and 23, we will follow these steps:

### Step 1: Perform the Addition
First, we need to add the three numbers together.

\[ 154.21 + 6.142 + 23 \]

Calculating this step-by-step:

1. Add 154.21 and 6.142:
\[ 154.21 + 6.142 = 160.352 \]

2. Now add 23 to the result:
\[ 160.352 + 23 = 183.352 \]

So, the sum of the three numbers is:
\[ 183.352 \]

### Step 2: Determine the Correct Number of Significant Figures
Next, we need to report the answer with the correct number of significant figures. The number of decimal places in the final answer should be determined by the number with the least number of decimal places in the original numbers.

- **154.21** has 2 decimal places.
- **6.142** has 3 decimal places.
- **23** has 0 decimal places.

The number with the least decimal places is **23**, which has 0 decimal places. Therefore, we will round our answer to the nearest whole number.

### Step 3: Round the Result
Now we round 183.352 to the nearest whole number:
- Since the digit after the decimal (3) is less than 5, we round down.

Thus, the correctly reported answer is:
\[ 183 \]

### Final Answer
The correctly reported answer of the addition of 154.21, 6.142, and 23 is **183**.
