The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r), a=initial term and r=common ration so
s(n)=20(1-0.25^n)/(1-0.25)
s(5)=20(1-0.25^5)/(0.75)
s(5)=26.640625

simplify to 12.85
12.85× X = 300
X=24
Answer:
15
Step-by-step explanation:
Applying,
The angle bisector theorem of triangle
From the diagram,
Since ΔAMT is an issoceless triangle,
Then,
Line OA divides Line MT into two equal parts.
Therefore,
Line MO = Line OT.............. Equation 1
From the diagram,
Line MO = 4x-1, Line OT = 3x+3
Substitute into equation 1
4x-1 = 3x+3
Collect like terms
4x-3x = 3+1
x = 4.
Therefore,
OT = 3(4)+3
OT = 12+3
OT = 15
