Find the common ratio for the following sequence. 64, 16, 4, 1, -4 -1/4 1/4 4

Step-by-step explanation:

THe sequence 64,16,4,1 as you can see it´s actually going down or decreasing, so the ratio should be a fraction, in order to find that you just have to pair two terms that are next to eachother in the sequence to find the fraction, let´s try it with the first two: 64 and 16:

So the ratio is 1/4. You can confirm the ratio by using other numbers in the sequence, like the last two:

This is the ratio directly.

faster, im not sure why but i know it is faster
