Which equation could be used to calculate the sum of the geometric series?

1/3 + 2/9 + 4/27 + 8/81 + 16/243

The equation is:

The sum is:

--------------------------------------------------------------------

If the sequence is infinite, the formula is:

-------------------------------------------------------------------

Step-by-step explanation:

We must calculate the radius of the geometric series

The first term of the series is:

The last term of the series is:

If the sequence is finite then the formula is:

If the sequence is infinite then by definition as the radius  are then the formula for the sum of the geometric sequence is:

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this
