Identify The Sequences That Have A Common Ration Of 4 Select All That Apply class=

Sagot :

In mathematics, a ratio indicates how many times one number contains another.

in this case, the ratio is 4

1)

2, 6, 10, 14, ...

2*4 = 8, which is different to 6 so the ratio is different to 4

2)

1, 4, 16, 64,...

1*4 = 4

4*4 = 16

16*4 = 64

In this case, the sequence has a common ratio of 4

3)

1600, 400, 100, 25, ...

1600*1/4 = 400

400*1/4 = 100

100*1/4 = 25

For this sequence the common ratio is 1/4. So it doesn't apply

4)

2, 8, 32, 128, ...

2*4 = 8

8*4 = 32

32*4 = 128

as in the 2nd case, this sequence also has a common ratio of 4

5)

16, 12, 8, 4,...

16*4 = 64

the ratio is different to 4

6)

1/2, 1/8, 1/32, 1/128

1/2*4 = 4/2 = 2

1/2*1/4 = 1/8

Again, in this sequence the common ratio is 1/4. So it doesn't apply

From the above, the sequences that have a common ratio of 4, are: 2) and 4)
