Answer 1

Question:

Solution:

If we need to calculate the sum of squares of n consecutive natural numbers, the formula is:

`\sum ^n_(k\mathop=1)k^2\text{ = }(n(n+1)(2n+1))/(6)`

the above formula can be proved by applying mathematical induction. Now, if we apply this formula, we get the solution:

`\sum ^6_(k\mathop=1)k^2\text{ = }(6(6+1)(2(6)+1))/(6)=91`

so that, we can conclude that the correct answer is:

`91`
