Step-by-step explanation:
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference that must Be equal
d=6-2=4 not equal to d=18-6=12
So it is not arithmetic
but when we get the common ratio that also must be equal
r=6/2=18/6=54/18=3 equal
So it is geometric
By using this equation:
a(n)=a(1)*r^(n-1)
and we have a(1)=2 , r=3
<u>Explicit rule:</u> a(n)=2*(3)^(n-1)
<u>Recursive rule:</u> a(n)= r * a(n-1)
a(n-1) ⇒ priviuse term
SO: a(n)= 3 * a(n-1)
For example:
a(3)= 3 * 6 =18

Answer:
55.6%
Step-by-step explanation:
1. The difference between 45 and 70 is 70-45=25 (If it is postive is an increase, if negative a decrease)
2.The base of comparison is the original number: 45
3. With both, you divide the difference with the base:
25/45 and you multiply it by 100 to get a %
4. Equation: ((70-45)/45)*100 = 55,55555555555
5. Rounded to the nearest above: 55,6%
The total number of games played would be 98
