-27x3 = -81 :) hope this helped you out

81 727 4949 is the answer

-81 is the answer because you need to multiply 3 to each number to get the next

243, 729

Step-by-step explanation:

The pattern of the set of data is multiplying each number by three to get the next number. So the next 2 numbers would be:

81*3=243

243*3=729

Hope this helps!

This appears to be a geometric sequence with a common ratio of 3. The next three numbers are ...

27*3 = 81

81*3 = 243

243*3 = 729

This numerical sequence has a pattern of times 3:

1*3=3*3=9*3=27*3=81...

Now that you know the pattern of sequence you can determine the next two terms:

81*3=a

a*3=b

b*3=c

81*3=243

243*3=729

and so on...

[tex]1,3,9,27 what are the next 5 numbers? and what is the nth term please show working out[/tex]

81, 243, 729, 2187, 6561

Step-by-step explanation:

Note that the

third term 9 = 3²

fourth term 27 = 3³

Thus to obtain a particular term in the sequence we require the exponent to be one less than the terms position n in the sequence, that is

[tex]a_{n}[/tex] = [tex]3^{n-1}[/tex] , thus

first term 1 → [tex]3^{1-1}[/tex] = [tex]3^{0}[/tex] = 1

The next 5 terms in the sequence are

[tex]a_{5}[/tex] = [tex]3^{5-1}[/tex] = [tex]3^{4}[/tex] = 81

[tex]a_{6}[/tex] = [tex]3^{6-1}[/tex] = [tex]3^{5}[/tex] = 243

[tex]a_{7}[/tex] = [tex]3^{7-1}[/tex] = [tex]3^{6}[/tex] = 729

[tex]a_{8}[/tex] = [tex]3^{8-1}[/tex] = [tex]3^{7}[/tex] = 2187

[tex]a_{9}[/tex] = [tex]3^{9-1}[/tex] = [tex]3^{8}[/tex] = 6561
