Hi there!
The answer is D. 21, 25, 29
The arithmetic sequence has a pattern of +4. From 17 you add 4, resulting to 21 and you continue.
Hope this helps !
Answer:
4 Terms.
Step-by-step explanation:
5x4
6x3
-2x
7 are all of the terms in the expression.
Commutative property of multiplication is what the property is called.
A * B = B * A
Where both 'A' and 'B' are expressions.
Hope this helps!
A(n)=ar^(n-1) and we can find the rate upon using the ratio of two points...
50/1250=1250r^2/1250r^0
1/25=r^2
r=1/5 so
a(n)=1250(1/5)^1=250
...
You could have also found the geometric mean which is actually quite efficient too...
The geometric mean is equal to the product of a set of elements raised to the 1/n the power where n is the number of multiplicands...in this case:
gm=(1250*50)^(1/2)=250
