Find the common ratio for the following geometric sequence 2, 1, 0.5, 0.25

 The correct option is (C) 0.5.

Step-by-step explanation:  We are given to find the common ratio for the following geometric sequence :

2,   1,   0.5,   0.25,   .   .   .

We know that

in a geometric sequence, the ratio of any term to its preceding term is the required common ratio of the sequence.

In the given sequence <a(n)>, we have

So, we get

Thus, the required common ratio for the given geometric sequence is 0.5.

Option (C) is CORRECT.

3x + 4y -25 =0 represents the amount of change sianna should recieve

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
