+Have the function ArithGeo(arr) take the array of numbers stored in arr and return the string "Arithmetic" if the sequence follows an arithmetic pattern or return "Geometric" if it follows a geometric pattern. If the sequence doesn't follow either pattern return -1. An arithmetic sequence is one where the difference between each of the numbers is consistent, where as in a geometric sequence, each term after the first is multiplied by some constant or common ratio. Arithmetic example: [2, 4, 6, 8] and Geometric example: [2, 6, 18, 54]. Negative numbers may be entered as parameters, 0 will not be entered, and no array will contain all the same elements.
+Examples
+Input: [5,10,15]
+Output: Arithmetic
+Input: [2,4,16,24]
+Output: -1

+First Factorial
+
+
+Have the function FirstFactorial(num) take the num parameter being passed and return the factorial of it. 
+
+For example: if num = 4, then your program should return (4 * 3 * 2 * 1) = 24. For the test cases, the range will be between 1 and 18 and the input will always be an integer.
+Examples
+Input: 4
+Output: 24
+Input: 8
+Output: 40320

+Word Count
+Have the function WordCount(str) take the str string parameter being passed and return the number of words the string contains (e.g. "Never eat shredded wheat or cake" would return 6). Words will be separated by single spaces.
+Examples
+Input: "Hello World"
+Output: 2
+Input: "one 22 three"
+Output: 3
