find the general term of the arithmetic sequence 3,-1 ,-5 ,-9

Each is 4 less than the one before.

the choices are an=7+4n , an=7-4n , an=3+4n, an=3-4n

is it an=3-4n ?

Yes. 3 - 4n

thank you

are you there?

You're welcome.

To find the general term of an arithmetic sequence, we need to identify the common difference and the first term.

In this given sequence, the first term (a₁) is 3. To find the common difference (d), we can subtract any two consecutive terms. By subtracting -1 from 3, we get 4. Similarly, subtracting -5 from -1 gives us 4, and subtracting -9 from -5 also gives us 4. Therefore, the common difference is 4.

Now that we have the first term (a₁ = 3) and the common difference (d = 4), we can find the general term (aₙ) using the formula:

aₙ = a₁ + (n - 1) * d

Here, n represents the position of the term in the sequence that we want to find.

Let's substitute the values into the formula:

aₙ = 3 + (n - 1) * 4

Simplifying further:

aₙ = 3 + 4n - 4

Combining like terms:

aₙ = 4n - 1

Therefore, the general term of the arithmetic sequence 3, -1, -5, -9 is 4n - 1.
