Explanation

Multiples of 3 between 4 and 97 are 6, 9, 12, ... 96

First number = 6

Last number = 96

Total numbers = 31

Sum = 31/2 x (6 + 96) = 31/2 x 102 = 31 x 51 = 1581

Explanation

• Odd numbers are integers that are not divisible by 2.
• They can be expressed in the form 2n + 1, where n is any integer.
• This formula always produces odd values like 1, 3, 5, 7, etc.
