### Example Question #32 : Sequences And Series

Find the sum of the first terms of the following arithmetic sequence:

**Possible Answers:**

**Correct answer:**

To find the sum of a certain number of terms in an arithmetic sequence, use the following formula:

- the number of the terms you have
- the first term of the sequence
- term of the sequence

To find the sum, we need to first find the 8th term of the sequence.

To find any term in an arithmetic sequence, use the following formula:

- is the term we want to find
- is the first term of the sequence
- is the number of the term we want to find
- is the common difference

Using the information given from the question,

Now, plug in the information to find the value of the 8th term.

Now that we know the 8th term of the sequence, we can plug in that value into the equation for the sum to find what these first 8 terms add up to.

### Example Question #11 : Other Arithmetic Sequences

Find the sum of the first terms of the following arithmetic sequence:

**Possible Answers:**

**Correct answer:**

To find the sum of a certain number of terms in an arithmetic sequence, use the following formula:

- the number of the terms you have
- the first term of the sequence
- term of the sequence

To find the sum, we need to first find the 9th term of the sequence.

To find any term in an arithmetic sequence, use the following formula:

- is the term we want to find
- is the first term of the sequence
- is the number of the term we want to find
- is the common difference

Using the information given from the question,

Now, plug in the information to find the value of the 9th term.

Now that we know the 9th term of the sequence, we can plug in that value into the equation for the sum to find what these first 9 terms add up to.

.

### Example Question #1 : How To Find The Nth Term Of An Arithmetic Sequence

An arithmetic sequence begins as follows:

Which of the following terms is the first positive term in the sequence?

**Possible Answers:**

The thirty-seventh term

The thirty-ninth term

The fortieth term

The sequence has no positive terms.

The thirty-eighth term

**Correct answer:**

The fortieth term

The common difference of the sequence is

,

so the th term of the sequence is

To find out the minimum value for which , set up this inequality:

The first positive term is the fortieth term.
