# What is the sum of first 2 natural numbers?

## What is the sum of first 2 natural numbers?

The formula of the sum of first n natural numbers is S=n(n+1)2 . If the sum of first n natural number is 325 then find n.

## What is the difference between the sum of first 2n natural numbers and the sum of first n odd natural numbers?

The difference between the sum of the first 2n natural numbers and the sum of the first r odd natural numbers is m+n 21m- 2n2 +n.

What is the sum of the whole number and natural number?

The sum of 1 and 0 is what we require. The sum of the smallest natural number and smallest whole number is 1. Note: In order to solve these types of questions first of all remember the basic definitions of the numbers. Some of them are defined as, the whole numbers are the numbers starting at 0 and counting up forever.

What is the difference between sum of the first n odd numbers?

The sum of n terms of an AP is given by the formula Sn= n/2 × [a + l]. Therefore, we have proved that the sum of first n odd numbers is equal to n2.

### What is the sum of first n natural odd numbers?

n2
The first n odd natural numbers are given by 1,3,5,7,9…… (2n – 1) and this forms an AP. The sum of first n odd natural numbers is n2.

### What is the difference between whole and natural numbers?

The only difference between natural and whole numbers is the value of 0. The whole number includes 0, whereas natural numbers do not.

Is all natural numbers are whole numbers?

The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered “whole numbers.” All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.

What is the formula of whole number?

The whole numbers are the numbers without fractions and it is a collection of positive integers and zero. It is represented by the symbol “W” and the set of numbers are {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,……………}. Zero as a whole represents nothing or a null value. Whole Numbers: W = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10……}

#### Are all natural numbers also whole numbers?

For those of you who are unfamiliar with this series, which has come to be known as the Ramanujan Summation after a famous Indian mathematician named Srinivasa Ramanujan, it states that if you add all the natural numbers, that is 1, 2, 3, 4, and so on, all the way to infinity, you will find that it is equal to -1/12.

What is the difference between the smallest whole number and smallest natural number?

The basic difference between natural numbers and whole numbers is that natural numbers do not include the number 0 and here the smallest number is 1. Whereas, whole numbers include 0, and here the smallest number is 0.

## What is difference between sum of even and odd numbers?

Sum of an even number and an odd number is always an odd number.

## What is the sum of n odd numbers?

= n2
We can also the sum of n odd numbers formula can be expressed as: Sum of n odd numbers = n2 where n is a natural number.

What is the mean of the sum of n odd natural numbers?

The arithmetic mean of first n odd natural number is (1) n^2 (2) 2n (3) n (4) 3n. This is an A.P. Hence option (3) is the answer.

Is every natural number a whole number?

The given statement is True. Every natural number is a whole number because integers are those numbers which are starts from 0 to infinity positive and negative and natural numbers are those numbers which are starts from 1 to infinite positive numbers. Natural numbers are all positive integers.
