Question

Heeeelp

Answer 1

give me the explicit formula that produces the given sequence...\[\frac{ 3 }{ 2 }, \frac{ 3}{ 4 },\frac{ 3 }{ 8 },\frac{ 3 }{ 16 }\]

Answer 2

can u write the question ?
i cant see it ...
I see an error just :(

Answer 3

their fractions...

Answer 4

3/2,3/4,3/8,3/16

Answer 5

Is it your mean ?
32/10 , 34/10 , 38/10 , 316/100 ?

Answer 6

ummm no, the fractions in the sequence are 3/2,3/4,3/8,3/16

Answer 7

its a geometric sequence

Answer 8

observe that each successive term is getting multiplied by 1/2

Answer 9

OK !
My means was are they your numbers ?

Answer 10

that means, \(r = 1/2\)
first term \(a = 3/2\)

then, we have the explicit formula for geometric sequence :-

\(\large a_n = ar^{n-1}\)

Answer 11

substitute, a and r values above

Answer 12

\(\large a_n = \frac{3}{2} (\frac{1}{2})^{n-1}\)

Answer 13

@ganeshie8 :Thank u friend :)
