Let's create a multiplication table using recursion! Our function will get two arguments:

1. The first number of the multiplication table
2. How many rows we want

Each row will be 8 numbers long and have the input number first, with each number after it multiplied by two. For example, if our first argument is 10:

[[10, 20, 40, 80, 160, 320, 640, 1280]]

Then, the next row will start with the first number of the last row + 1. For example, the first arg (starting num) is 10 and second (num of rows) is 3:

[[10, 20, 40, 80, 160, 320, 640, 1280],

[11, 22, 44, 88, 176, 352, 704, 1408],

[12, 24, 48, 96, 192, 384, 768, 1536]]

The function should return a 2D array with each row represented as an array, as depicted above. Remember to try this with recursion!!
