<u>Arithmetic Sequences</u>
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the first terms of a sequence:
-12, -28, -44,...
Find the common difference by subtracting consecutive terms:
r = -28 - (-12) = -16
r = -44 - (-28) = -16
The first term is a1 = -12. Now we calculate the term n=61:

Step-by-step explanation: Formula to find an area of a triangle A= 1/2base x height
Data
h=12mm A=1/2 base x height
b=14mm. A= 1/2 x (14mm x 12mm)
A=? A= 168mm^2(square) /2
A= 84mm square
Take $360.00 and multiply by .944 and that equals $339.84
