When the same number is repeated as a factor three times -- as 4 × 4 × 4 -- we call the product the 3rd power of that base; that product is commonly called a cube. (This is analogous to the volume of the solid figure called a cube.) Here is number 4: Upon repeatedly adding it four times --

Simple approach: Find sum series for every value from 1 to N and then add it. Create a variable Total_sum to store the required sum series. Iterate over the number from 1 to N.
