Given: Natural numbers ranging from 21 to 50

To find: Sum of these numbers

Explanation: The sum of natural numbers from 1 to some natural number n is given by the formula: n(n+1)/2.

Sum of natural numbers from 21 to 50 can be found by: Sum of 1 to 50- Sum of 1 to 20

Sum of 1 to 50= n(n+1)/2 where n= 50

= 50*51/2

= 25*51

= 1275

Sum of 1 to 20 = n(n+1)/2 where n = 20

= 20*21/2

= 10*21

= 210

Therefore, sum of natural numbers from 21 to 50 = 1275-210

= 1065

Therefore, the sum of natural numbers between 21 to 50 is 1065.
