No. A series is just a list of numbers, with some kind of 'rule' that tells you how you get from one number to the next one. What you have in your question looks like a sum, all ready to get added up.
A number is called a staircase composite number when it has three prime factors that have different sized digits: the first is one digit, the second is two digits and the third is three digits. For example: [7] [41] [271] x 77 777 77 777 would be the staircase composite number.
