What is the 4th partial sum for the geometric sequence where a1=18 and r = 2? Explain your steps in words or attach a screenshot of your work.

glizxzy:

a4= 144

angelfish:

with what

MiraAngel:

lol Thanks for the answer! Do you have the steps?

glizxzy:

to find a4 we use formula An= a1* rn- 1 in this example we have a1= 18, r= 2, n= 4. After substituting these values to above formula, we obtain: An= a1* rn- 1 a4= 18 *24- 1 a4= 18* 8 a4= 144
