Sum of 1 + 3 + 5 + 7 + ........ + 35 is 324

Solution:

Given that, we have to find the sum

Given is:

1 + 3 + 5 + 7 + ........ + 35

The sum of n odd numbers is given as:

The sum of any set of consecutive odd numbers starting with 1 is always equal to the square of the number of digits that were added together

Therefore,

Sum = n^2

Here, total odd numbers from 1 to 35 is 18

Sum = 18^2\\\\Sum = 18 \times 18\\\\Sum = 324

Thus sum is 324
