Plug in n = 1 into the nth term formula
a(n) = 4n-1
a(1) = 4*1-1
a(1) = 3
So the first term is 3
The second term will be 7 because we add on 4 each time, as indicated by the slope of 4. This is also known as the common difference.
So the nth term is found by adding 4 to the (n-1)st term, in other words,
a(n) = a(n-1)+4
----------------------------------------------------------------------------
In summary, the answer is
a1=3; an=an-1+4
which is choice B
Answer:
I would say its the bottom one
Step-by-step explanation:
The top one goes to five while the bottom only goes to four, plus you cant have a negative amount of people you can only have from 0 to infinity amount of people.
angle 2 is congruent to angle six
Answer:
Step-by-step explanation:
The graph shown is f(x)=y=|x|
The required graph is g(x) = |x|-3 = f(x) -3
In general, the graph of f(x)-3 is 3 units below f(x), and has the same shape.
See attached graph. y=f(x)=|x| in blue, f(x)-3 = |x|-3 in red.
