Step-by-step explanation:
Arithmetic:
a(n) = a +(n-1)d
a=15
d=5-15=-10
°.° a(n) = 15 +(n–1)-10
Geometric:
a(n)=a*r^(n-1)
a=15
r=5/15=1/3
a(n)=15*(1/3)^(n-1)

Answer:
3⋅(5⋅x)
5⋅(x⋅3)
15x
Step-by-step explanation:
As the values are inside the brackets, it does not matter what side the (x3) is on, so 3⋅(5⋅x) is equivalent.
Multiplying the contents of the brackets in the third one (x * 3) by 5 gives the same value as 3 * (x * 5) so 5⋅(x⋅3) is also equivalent.
On multiplying the brackets out:
5 * x = 5x
5x * 3 = 15x
So 15x is also equivalent.
