I think this is very easy:
 var myVars={"Numbers":[{"1":6},{"2":19},{"3":34},{"4":38},{"5":70}],"MB":5,"MP":"05","DrawDate":"2016-03-22T00:00:00"} 
myVars.Numbers will give you: [{"1":6},{"2":19},{"3":34},{"4":38},{"5":70}] This element represents an array: the first element is myVars.Numbers[0] - {"1":6} , the second is myVars.Numbers[1] - {"2":19} . Finaly, myVars.Numbers[1][2] is 19. This means that if you want to access the second number 19 , you need to write: myVars.Numbers[1][2]
