+# Exercise  - recursiveFibonacci
+
+Write a *recursive* function `recursiveFibonacci` that takes a number `n` and returns an array
+containing that many numbers from the Fibonacci sequence.
+
+You should already be familiar of what the fibonacci series is from an earlier exercise, but in case you have forgotten, each term in a fibonacci series is defined as the sum of the previous two terms.
+
+The first term of the fibonacci series is `1` and so is the second term `1` too. From there, we can find the rest of the fibonacci series.
+
+An example:
+
+```javascript
+recursiveFibonacci(8); // [0, 1, 1, 2, 3, 5, 8, 13]
+```
