It's dividing by 2.

Next 3 would be: 25, 25/2, 25/4 or converting those into decimals.

Hi there! The geometric sequence is 1/2 of the number, because 400/2 is 200, 200/2 is 100, 100/2 is 50 and so on. 50/2 is 25, 25/2 is 12.5 and 12.5/2 is 6.25. There. The next three patterns of the geometric sequence is 25, 12.5, and 6.25.

If (-1, y) lies on the graph of y=2^2x then y=

zubka84 [21]

Answer:

y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.

I believe the equation to be $y=2^{2x}$ . If you meant $y=2^2x$ , please let me know.

Thanks kindly.

Step-by-step explanation:

If (-1,y) lies on the graph of $y=2^{2x}$ , then by substitution we have:

$y=2^{2\cdot -1}$ .

We just need to simplify to determine y:

$y=2^{2 \cdot -1}$

Multiply the 2 and -1:

$y=2^{-2}$

Use reciprocal rule for exponents to get rid of the negative:

$y=\frac{1}{2^2}$

$2^2$ just means $2(2)$ :

$y=\frac{1}{2(2)}$

$y=\frac{1}{4}$ .
