Match the parts of the following function with their correct definitions.
a(n) = a + (n - 1)d
1) a(n) a) common difference
2) a b) value of the nth term
3) n c) value of the first term
4) d d) number of the nth term

1) A(n) - B) value of the nth term; 2) a C) value of the first term; 3) n D) number of the nth term; and 4) d A) common difference

Step-by-step explanation:

In an arithmetic sequence, A(n) stands for the general, or nth, term.  a is the value of the first term; d is the common difference (what we add each time); and n is the term number (what we replace with a number to find the term we're after).

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
