The geometric mean of two postitive numbers a and b is sqrt(ab). Show that for f(x) = 1/x on any interval [a,b] of positive numbers, the value of c in the conclusion of the mean value theorem is c = sqrt(ab) I have no idea how to do this! If the mean of a and b is sqrt(ab), ...

Please help--Geometric series
your title says, "geometric series" none of them are a geometric series 1) I think you have a typo and meant 5/1 + 8/1 + 11/1 + 14/1 + . . first of all the 1's in the denominator are redundant and you are simply looking at 5 + 8 + 11 + 14 + ... which is (3n+2) with n starting ...

Geometric series - Check my answer
What is the first term in a geometric series with ten terms, a common ratio of 0.5 and a sum of 511.5? I got 256 as my answer. 511.5=a1[1-(.5)^10]/1-1/2 511.5=a1(1023/1024)/1/2 511.5=a1(1023/512) ----> divide by both sides 256=a1
