Finding the general term of a sequence
Hi, Everyone!
Two circles C and D of radius 1 touch each other at point P. T is a
common tangent line for C and D; C1 is the circle that touches C, D and
T; C2 is the circle that touches C, D and C1; C3 is the circle that
touches C, D and C2. This procedure could be continued indefinetely and
produces an infinite sequence of circles {Cn}. Find the expression for
the diameter of Cn.
Thank You Very Much!
