☃️Question:

Take any 2, any 3, any 4, any 5 odd numbers and find their sum. What do you observe in the results obtained?

☄Answer:

Let's take 2 odd numbers:

Odd numbers are: 3, 5, 7, 9, 11, 13....

= 3 + 5 = 8. (8, an even number)

Let's take 3 odd numbers:

= 3 + 5 + 7 = 15 (15, an odd number)

Let's take 4 odd numbers:

= 3 + 5 + 7 + 9 = 24 (24, an even number

Let's take 5 odd numbers:

= 3 + 5 + 7 + 9 + 11 = 8 = 35 (35, an odd number)
