Which equation could be used to calculate the sum of the geometric series? 4+1+14+116+164

Recall that Sn=a1(1−rn)(1−r)

Group of answer choices

S5=14(1−(4)5)(1−4)

S5=4(1−(14)5)(1−14)

S5=4(1−14)

S5=14(1−4)

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
