Question

Sum of first 10 odd natural numbers is​

Answer 1

Answer:

The first 10 odd numbers are

1, 3, 5, 7, 9, 11, 13, 15, 17,19

The standard mathematical method of getting the sum of a series would be to add the first number of the series to the last number of the series and multiply the sum by one half the number in the series.

1 + 19 = 20

20 × 5 = 100 ( there are 10 odd numbers in the series, so half of them would be 5.

Thus the sum is 100

Natural numbers :

Natural numbers are those that begin with one and conclude with infinity. To put it another way, we looked at natural numbers as a set of whole numbers that did not include the number 0.

Odd numbers :

• When an odd number is divided by two, it either leaves a remainder or produces a fraction. The first odd positive number is one, but there is no remainder.

Step-by-step explanation :

• First 10 odd natural numbers are 1,3,5,7,9,11,,13,15,17,19.
• Sum of first 10 odd natural numbers is

           1 + 3 + 5 + 7 + 11 + 13 + 15 + 17 + 19 = 100

So , Sum of first 10 odd natural numbers is​ 100
