Tell whether the sequence is arithmetic. if it is identify the common difference 1/2, 1/3,1/4

For this case we have the following definition:

An arithmetic sequence is a sequence of numbers that increases or decreases by a constant amount each term.

Thus, to obtain it is necessary to subtract from the amount of .

To obtain it is necessary to subtract the amount of .

As it is observed, a constant quantity is not diminished since is not equal .

So, the sequence is not arithmetic

The sequence is not arithmetic

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
