Answer:
To find the sum of the first five natural numbers, you can follow this algorithm:
1. Initialize a variable, let's call it "sum," to keep track of the running total. Set the initial value of "sum" to 0.
2. Use a loop to iterate over the first five natural numbers (1, 2, 3, 4, 5). Start the loop from 1 and continue until 5.
3. In each iteration of the loop, add the current natural number to the "sum" variable.
4. After the loop completes, the "sum" variable will contain the sum of the first five natural numbers.
Here's the algorithm in pseudocode:
```
sum = 0
for i from 1 to 5:
sum = sum + i
end loop
```
By following this algorithm, you can calculate the sum of the first five natural numbers. In this case, the sum would be 1 + 2 + 3 + 4 + 5 = 15.
