Answer: 4 radical 10

Reason:
First you have to add 3 radical 2 and radical 2, getting 4 radical 2.

Then you multiple 4 radical 2 by 2 radical 5 and you get 8 radical 10.
Then you divide that by 2 to get the area of a triangle so then it comes back to 4 radical 10

What is the sum of the first five terms of a geometric series with a1 =20 and r =1/4?

drek231 [11]

The sum of the first n terms in a geometric sequence given the first term (a1) and the common ratio (r) is calculated through the equation,

Sn = (a1(1−r^n) / (1−r)

Substituting the known terms,
Sn = (20)(1 - (1/4)^4)) / (1 - 1/4)
Sn = 26.5625

Thus, the sum of the first four terms is 26.5625.
