Write a recursive rule for the sequence: 2, 8, 32, 128, 512,. . . (NO LINKS!!!)​

bruv what are u doin its litterly *4 every time

Step-by-step explanation:

a1 =2

an = an-1  * 4

Step-by-step explanation:

We can tell this is geometric by the way it increases

To find the common ratio, take the second term and divide by the first term

8/2 =4

Check to make sure

2*4=8

8*4 =32

32*4 =128

The recursive formula is

a1 = the first term

an = an-1 *r

a1 =2

an = an-1  * 4

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.
