# Looping Exercises

From WLCS

**Objective:**

- To become well-learned in the way of the while loop

**Resources:**

**Directions:**

- For each of the following sequences,
**first prompt the user for a number N** - Use while loops to generate the following sequences

**Powers of 2**- Print out the first N terms of the sequence
- 1, 2, 4, 8, 16, 32, 64, 128, ...

**Fractions Sequence**- Print out the first N terms of the sequence
- 1/1, 1/2, 1/3, 1/4, 1/5, ...

**Summation up to N**- Use a loop to add up all the numbers from 1 up through N
- Example: N = 3 would total 6
- Example 2: N = 10 would total 55

**Fibonacci Sequence (HINT: use multiple variables)**- Print out the first N terms of the sequence
- 0, 1, 1, 2, 3, 5, 8, 13, 21, ...

**Factorial Sequence (HINT: use multiple variables)**- Print out the first N terms of the sequence
- 1, 1, 2, 6, 24, 120, ...
