Suppose sn is defined as 2 + 22 + 23 + . . + 2n . what is the next step in your proof of sn = 2(2n - 1), after you verify that sn is valid for n = 1?
a. show that sn is valid for n = k + 2.
b. assume that sn is valid for n = k .
c. verify that sn is valid for n = 1.
d. show that sn is valid for n = k.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
