Which rule best described the following pattern 8,4,10,6,12,8,14

-4 and +6

Step-by-step explanation:

The sequence follows a pattern of subtracting 4 then adding 6.

8 - 4 = 4 + 6 = 10 - 4 = 6 + 6 = 12 - 4 = 8 + 6 = 14

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
