What is the mean of these numbers 1.2 1.4 1.5 1.7 and two

To find the mean (average) of a set of numbers, you sum all the numbers and then divide by the total count of the numbers.

Given the numbers:  
1.2, 1.4, 1.5, 1.7, and 2.

1. **Sum the numbers:**  
\(1.2 + 1.4 + 1.5 + 1.7 + 2 = 7.8\)

2. **Count the numbers:**  
There are 5 numbers.

3. **Calculate the mean:**  
\[
\frac{7.8}{5} = 1.56
\]

Thus, the mean is **1.56**.
