Write 22.056 in an expanded form

Sidana [21]

We know the first place after decimal is tenths

The second place after decimal is hundredths

The third place after decimal is the thousandths place

So for 0.056

0 is at the tenths place

5 is at the hundredths place

and 6 is at the thousandths place

Expanding 22.056 we get

22.056 = 20 + 2 + 0.05 + 0.006

22.056 = $20+2+\frac{5}{100}+\frac{6}{1000}$

Explicit equation for the sequence

Jlenok [28]

Step-by-step explanation:

when we get the common ratio that must be equal

r=6/2=18/6=54/18=3 equal

So it is geometric

By using this equation:

a(n)=a(1)*r^(n-1)

and we have a(1)=2 , r=3

Explicit rule: a(n)=2*(3)^(n-1)

hope this helps
