- [0](https://md.mova.elamur.ai/free/en/corpora/school/lessons/183-odd-numbers-in-a-range/0/) — Odd and even numbers take turns, so in a range about half of the numbers are odd; the ends decide whether it is one more or one less.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/lessons/183-odd-numbers-in-a-range/1/) — From 1 up to a number there are as many odd numbers as half of the number, rounded up: from 1 to 9 there are 5, from 1 to 10 also 5.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/lessons/183-odd-numbers-in-a-range/2/) — From 14 to 31: odd numbers from 1 to 31 are 16, from 1 to 13 are 7, so from 14 to 31 there are 16 - 7 = 9.
