Question

Calculate the average of the numbers: 255,172,315,-393, - 243,194

Answer 1

To calculate the average of the numbers 255, 172, 315, -393, -243, and 194, follow these steps:

1. **Sum the numbers**:
\[
255 + 172 + 315 + (-393) + (-243) + 194
\]

Breaking this down step-by-step:
\[
255 + 172 = 427
\]
\[
427 + 315 = 742
\]
\[
742 - 393 = 349
\]
\[
349 - 243 = 106
\]
\[
106 + 194 = 300
\]
So, the sum of the numbers is **300**.

2. **Count the numbers**:
There are 6 numbers in total.

3. **Calculate the average**:
\[
\text{Average} = \frac{\text{Sum of numbers}}{\text{Total count of numbers}} = \frac{300}{6} = 50
\]

Thus, the average of the numbers is **50**.
