# Arithmetic progression

JavaScript, Math, Algorithm · Oct 13, 2021

Creates an array of numbers in the arithmetic progression, starting with the given positive integer and up to the specified limit.

- Use
`Array.from()`

to create an array of the desired length,`lim / n`

. Use a map function to fill it with the desired values in the given range.

```
const arithmeticProgression = (n, lim) =>
Array.from({ length: Math.ceil(lim / n) }, (_, i) => (i + 1) * n );
```

`arithmeticProgression(5, 25); // [5, 10, 15, 20, 25]`
