This is NOT an arithmetic sequence because there is no common difference. It is a geometric sequence because there is a common ratio. Meaning that each term is a constant ratio or multiple of the previous term. The recursive rule for this geometric sequence is:
a(n)=3*a(n-1), a(1)=3
Answer:
Step-by-step explanation:
all you need to do is use the distributive property and then you"ll get the answer
Answer:
5
Step-by-step explanation:
First the question said that two equal sides of the isosceles triangles is thrice the third side. This means that the two equal sides is 3x while the third side should be represented as x
Secondly, add the three parts together which = 3x+3x+x =7x
Thirdly, then divide both sides by 7= 7x/7 *35/7
Making x=5
