Honey, the 7th odd number is 13. You start with 1, then add 2 to get 3, add 2 again to get 5, add 2 more to get 7, add 2 more to get 9, add 2 more to get 11, and finally add 2 more to get 13. It's like counting on your fingers, but with a little extra math sass.

Oh, dude, the 7th odd number is 13. Like, odd numbers are those numbers that can't be divided evenly by 2, you know? So, if you start counting odd numbers from 1, the 7th one you hit is 13. Easy peasy lemon squeezy.
The 7th odd number is calculated by multiplying the position number (7) by 2 and subtracting 1. So, 7 * 2 - 1 = 14 - 1 = 13. Therefore, the 7th odd number is 13.

An odd number times an odd number is an odd number no matter which 2 odds you multiply.
If the last number is odd or even then the whole number is odd or even, in this case the last number is 3 which is an odd number, therefore the whole number is odd.
