Sure, let's find the arithmetic mean (average) of the given numbers 1, 32, 53, 45, and 2560 step-by-step:

1. List the Numbers:
The numbers we need to find the average of are 1, 32, 53, 45, and 2560.

2. Sum the Numbers:
Add all the numbers together:
[tex]\[ 1 + 32 + 53 + 45 + 2560 = 2691 \][/tex]

3. Count the Numbers:
There are 5 numbers in our list.

4. Divide the Sum by the Count:
Divide the sum of the numbers by the number of elements in the list:
[tex]\[ \frac{2691}{5} = 538.2 \][/tex]

So, the arithmetic mean (average) of the numbers 1, 32, 53, 45, and 2560 is 538.2.
