X = 59, y = 44
2x + 18 + x - 15 = 180
3x + 3 = 180
3x = 177
x = 59
x - 15 = y
59 - 15 = y
44 = y
Answer:
Rule = 759375(1/15)^(n-1)
Where n represent the number of term
Step-by-step explanation:
a5= ar^4= 15
a6= ar^5= 1
ar^4=15... Equation 1
ar^5=1.... Equation 2
Dividing equation 2 by equation 1
r= 1/15
For the value of a
ar^5=1
a(1/15)^5= 1
a(1/759375)= 1
a= 759375
Rule = 759375(1/15)^(n-1)
Where n represent the number of term
