Answer:
There's a treasure hunt called The amazing race this year I'll be participating with one other person. Her name is Fransterla as a result I will be the team leader. With this I will try my best to lead us to victory. The first task will be that they give us clues and a map, to find information for the journey that is up a head.
Factors of 5,1 factors of 4,2,1 factors of 2,1
(16 + 15 -10 +4) = 25
25 squared is 625
This is an arithmetic sequence because each term is 7 greater than the previous term, so 7 is what is called the common difference...
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=first term, d=common difference, n=term number.
We know a=1 and d=7 so:
a(n)=1+7(n-1)
a(n)=1+7n-7
a(n)=7n-6
The above is the "rule" for the nth term.
