Find the common ratio for this geometric sequence. 72, 12, 2, 1/3, 1/18

OA. 1/3
ОВ. 1/6
OC. 3
OD. 6

1/6

Step-by-step explanation:

We need to find the common ratio for the given Geometric Series . We know that ,

Geometric Series:- When a common number is multiplied to each term to obtain the next term of the Series is called Geometric Series .

Common Ratio :- The number which is multiplied to obtain the next term of the series .

Here the given series is ,

We can find the common ratio by dividing the consecutive terms , As ,

Substitute the respective values ,

Simplify by dividing the term in RHS ,

Hence the common ratio is 1/6 .

its the fourth option

yes because they have the same amount of green and blur marbles.
