I have a very confusing question. I need fixed sequence for the following numbers:

4 0.25 4 0.25 ......

The question is, how do i get from 4 to 0.25 bck to 4 nd then 0.25. I hve tried dividing by 16 nd multiplying by 16 which is wrong becuse it hs to be just one thing e.g either divde, subtrct, multiply or add. I hve not got an idea. Please help someone!

4 0.25 4 0.25 ......

o right i see wht u mean nw lol :lol:

Yes please! :thumbsup:

Term n = 1/(term n-1)

Admittedly copied from google!

i was thinking that but it doesnt really fit cos your not dividing by the same thing

Term n = 1/(term n-1)

Admittedly copied from google!

What does that mean?:?

as n increases it is either 1/4 or 4. I guess its something like that

Cosmicdav3 looks about right as well.

1/(1/4) = 4/1

1/(4/1) = 1/4

basically 1/previous answer..

This does give the answer 0.25 but does not go bck to 4 again. n can't change, it is constant.:oops:

1/(4/1) = 1/4

Its not constant

if n=2 then its 4^1 = 4

if n=3 then its 4^(-1) = 0.25 and so on

im not sure what you mean by n is a constant, i define n as the term in the sequence

so in this case the first term (when n=1) is 0.25, 2nd (when n =2) is 4 and so on.

it doesnt need to be... i was just showing you how it would work... the sequence is 1 divided by the previous number in the sequence..

if n=2 then its 4^1 = 4

if n=3 then its 4^(-1) = 0.25 and so on

im not sure what you mean by n is a constant, i define n as the term in the sequence

so in this case the first term (when n=1) is 0.25, 2nd (when n =2) is 4 and so on.

Well done! I think you have cracked it. :thumbsup:

1 divided by 0.25 = 4 ;-)

if n=2 then its 4^1 = 4

if n=3 then its 4^(-1) = 0.25 and so on

Yeah! Impressive!

4 - 3.75

& then

-(-3.75) to get back to 4

still using constant minus........ just my tuppennce worth mate
