Answer 1

Answer:

Step-by-step explanation:

An efficient solution is to use direct formula. To find the sum of first n odd numbers we can apply odd number theorem, it states that the sum of first n odd numbers is equal to the square of n. if we apply odd number theorem: sum of first 10 odd numbers = n * n = 10 * 10 = 100.
