What is the pattern you see when counting by tens

Only the number in the tens place increases by one and the ones place stays as 0 i. e. 10, 20, 30 ... you could do 1,2,3 ... and then just add a zero to the end of that number. when you reach ten keep going, i. e. 8,9,10,11,12,13 ... would end up being 80,90,100,110,120,130.
