In appending the array, the quotation marks around the "7" mean it is a String; arrays are 'homogenous' and can only accept one type of data like Ints, Strings, Doubles etc.

// arrayOfStrings would look like ["this", "is", "a", "string"]


The String concatenation you've done at the bottom passes the challenge too.

I hope this helps :)
