|
Answer» Answer: The family of natural numbers includes all the counting numbers, starting from 1 till infinity. If n consecutive natural numbers are 1, 2, 3, 4, …, n, then the sum of squared ‘n’ consecutive natural numbers is REPRESENTED by 12 + 22 + 32 + … + n2. In short, it is denoted by the notation Σn2. The formula for the ADDITION of squares of natural numbers is GIVEN below: Σn2 = [n(n+1)(2n+1)]/6 Step-by-step explanation: The family of natural numbers includes all the counting numbers, starting from 1 till infinity.
