Find the sum of the first 7 terms of the following sequence.

Round to the nearest
hundredth if necessary.

6,-10 ,50/3
Sum of a finite geometric series:

sn = a1-a1rn /1-r

20078/243

Step-by-step explanation:

sn = a1-a1r^n/1-r

sn = a1 * 1-r^n/1-r

s7 = 6 * 1 - (-5/3)^7/1-(-5/3)

s7 = 6 * 10039/729

s7 = 6 * 10039/243*3

s7 = 2 * 10039/243

s7 = 20078/243

answer

see attachment

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
