The fifth term of an arithmetic sequence is 11 and the tenth term is 41. what is the first term?

In this sequence, the first term is and every successive term is determined by

where is the common difference between terms. We have

so that

Then

The first term is -13.

Step-by-step explanation:

The general rule of an arithmetic sequence is the following:

In which d is the common diference between each term.

This is the case going from one term to the next. However, when, as in this problem, we have the fifth and the tenth term, this formula can be expanded, as the following way:

So

The common diference is 6.

To find the first term, we do:

The first term is -13.

answer: i cant see the picture

step-by-step explanation:

can u take a better picture

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
