Explain the pattern 322 and 32.2 and 3.22 and 0.322

We notice that 322 is 10 times of 32.2 and this pattern continues so

322/10=next term

so the equation is

the n'th term (exg, 1st 2nd, 3rd) is

3320 (0.1^n) so exg

the first term (1) is

3220 times (0.1^1) or 3220 times 0.1=322

2nd term

3220 (0.1^2) = 3220 times 0.001=32.2

and so on

The pattern is to divide by 10 each time like 322/100 it give you 32.2, and 32.2/10 it gives you 3.22 and 3.22/10 it gives 0.322
