Write the sum using summation notation, assuming the suggested pattern continues. 4 - 12 + 36 - 108 +

is the answer.

Step-by-step explanation:

The given pattern is in the form of 4 - 12 + 36 - 108

We can see that each successive term of the pattern is multiplied by (-3) or we can calculate the common ratio of each term is =

Now it is clear that it's an exponential pattern which will be in the form of

and we know sum of this exponential pattern is represented by

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
