How do you find the reciprocal of 3.6?? ...?

laiz [17]

you can turn 3.6 into a fraction, and then switch the numerator and denominator: 3.6 = 3.6/1 = 36/10
the reciprocal is
10/36 = 5/18
reduced the fraction by dividing the top and bottom by 2
you could ALSO say the reciprocal of:
3.6/1 is 1/3.6,
but i assume you're supposed to come up with a nice fraction...

A sequence of numbers begins with 12 and progresses geometrically. each number is the previous number divided by 2. which value

Viefleur [7K]

1/2 value can be used as the common ratio in an explicit formula that represents the sequence.

Definition of sequence -

The following of one thing after another; succession. order of succession: a list of books in alphabetical sequence.
A continuous or connected series: a sonnet sequence. something that follows; a subsequent event; result; consequence.

A sequence that progresses geometrically has the first term as 12.

Each number is the previous number divided by 2.

so the sequence will be 12, 6, 3, 1.5...........

Explicit formula of a geometric sequence is given by

$T_{n} = ar^{n-1}$
