The formula in getting the arithmetic sequence:
an = a1<span> + (n – 1)d.
</span>
We can substitute the values in order for us to know how many terms the sequence has.

an = 7373
a1 = 1313
d = 303

an = a1<span> + (n – 1)d
</span>7373 = 1313 + (n-1) 303
7373 = 1313 + 303n - 303
-303n = 1313 - 303 - 7373
303n = -1313 + 303 + 7373
303n = 6363
n = 21

So, there are 21 terms in the sequence given.

Solve for x in the following:<br> 8x^2 + 6x = -5
artcher [175]

Answer:

No solution or

(-3±2i\sqrt{31})/8

Step-by-step explanation:

To get the solution, move everything to the left side of the equation:

8x²+6x+5 = 0

If you try to factor the equation or graph it, you will see that it will never equal 0.

If you need an imaginary solution you can plug it into the quadratic equation:

-6±\sqrt{36-160} over 16

Simplify and you get

-6±i\sqrt{124} over 16

-6±4i\sqrt{31} over 16

Simplify the fraction and you can get

(-3±2i\sqrt{31})/8
