How do you write an algorithm to find the sum of the first n natural numbers?

How do you write an algorithm to find the sum of the first n natural numbers?

Pseudocode for finding the sum of Natural Number Declare a variable n, i and sum as integer; Read number n ; for i upto n increment i by 1 and i=1 { sum=sum+i; } Print sum; Here in this Algorithm we declare 3 variables n for storing the number, i for running the for loop and sum for storing the sum. Read the number n.

What is algorithm elementary math?

Math algorithms are step-by-step procedures specifying how to solve a problem, and the most common of them are the four basic procedures: addition, subtraction, multiplication and division.

What is the simplest way to add up the first 50 numbers?

This is the simplest way to add up the first 50 numbers. So, for n=50, the answer should be 50*51/2 = 1275. Originally Answered: What is an algorithm to find the sum of the first 50 numbers?

How to find even numbers from 1 to 100 using APL?

Both this and the bitwise & produce the same result. Here it is in APL. It reads +/ sum 2× 2 times ⍳50 the natural numbers from 1 to 50. Doubling each number from one to 50 gives you the even numbers from 2 to 100, then you simply execute the plus reduction on that list.

How do you find the sum of the first n integers?

Of course the best way to find the sum of the first n integers is n ( n + 1) 2. Let N ← the final number in the sum // In your case, it’s 50. Use your high school knowledge. The sum of any series of numbers say N = N* (N+1)/2 e.g. the sum of the first three numbers is 3* (4)/2=6.
