Let's say, The first eight terms of the numbers are given: 100, 111, 122, 133, 144, 155, 166, 170,...

So, when the last digit is between 0 to 5, add 11, and only when last digit is 6, add 4.

How can I find the formula to find out what is ***nth*** term in this sequence?
(given the first term can be any number)
