+Returns 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`, and a map function to fill it with the desired values in the given range.
+
+```js
+const arithmeticProgression  = (n, lim) => 
+  Array.from({ length: Math.ceil(lim / n) }, (v, i) => (i + 1) * n );
+```
+
+```js
+arithmeticProgression(5, 25); // [5, 10, 15, 20, 25]
+```
