Question

The average of first 23 natural number is

Answer 1

Answer:

Average of 23 natural numbers =Sum/23

We have

Sum of first 'n' natural numbers=n(n+1)/2

Sum=23×24/2

=276

Average=276/23=12

Answer 2

Answer:

Step-by-step explanation:

sum of first n numbers is = n(n+1)/2

here we need sum of first 23 natural numbers = 23 ( 23 + 1 ) / 2

                                          23 ( 24 ) / 2     =     276

now average of first 23 numbers is = sum of first 23 numbers ÷ 23

                                           = 276 / 23 = 12

Another method

given first 23 numbers

average for consecutive odd numbers is first number + last number ÷ 2

here first number is 1

last number is 23

average = 1 + 23 / 2     =    24 / 2    =  12

hope you likes on of the method mate
