Question

Find the next three terms of the sequence. Then write a rule for the sequence.

648, 216, 72, 24

Answer 1

8,4,2.....
or 8,8/3,8/9.....

Answer 2

if u tell me which one is rite i shall tell u the rule.......

Answer 3

Rohan think and reply.....

Answer 4

8,4,2.....
or 8,8/3,8/9.... it will be going on on and onnnnnnnn

Answer 5

u dont be a barrier

Answer 6

the rule plzzzzzz!

Answer 7

which one is rite 8,4,2 or 8,8/3,8/9

Answer 8

the second

Answer 9

the first

Answer 10

@Rohangrr ure wrong once again so thats why i said think and reply!

Answer 11

is the answer the 2nd

Answer 12

@daja2fly the rule is that see,
648 can be written as 2^3*3^4
216 can be written as 2^3*3^3
72 can be written as 2^3*3^2
24 can be written as 2^3*3^1
the next term will be 2^3*3^last power -1
then 2^3*3^0
then 2^3*3^-1
then 2^3*3^-2...
and so on....!!!!!

Answer 13

understood?

Answer 14

i get the sequence but not the actual rule how would i write that

Answer 15

u can write it as 2^3*3^last power-1
\[2^{3} \times 3^{x _{l}-1}\]

Answer 16

where
\[x _{l}\] is the previous power

Answer 17

ok?

Answer 18

This is a geometric series where the first term is 648 and the common ratio is 1/3. The next term would be 24(1/3) or 8, and the next is 8/3 etc. The expression for the nth term would be:\[a _{n}=(648)(1/3)^{n-1}\]. Substituting and solving for the fifth term:\[a _{5}=648(1/3)^{4}=648(1/81)=8\]
