Answer :

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
apologiabiology
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
