When a
1, any particular solution is obtained by determining a specific,
numerical value for I. In fact, a particular solution is determined by a specific,
numerical value J for any (particular) entry, S;. Solving the equation
J = 1+jc for I,
I = J– jc.
// since S; = I+jc
// where So =I
we get
// One particular “particular solution" has I = 0.

Example 8.2.1: The Towers of Hanoi
The recurrence equation for the number of moves in the Towers of Hanoi
problem is a first-order linear recurrence equation:
Tn = 2T,-1+1.

Here a = 2 and c =
1, so
1, and any sequence T that satisfies
1 - a

this RE is given by the formula
Tn = 2" [I – (–1)]+(-1)
= 2" [I+ 1] – 1.
Assuming T has domain N and denoting To by I, we saw at the beginning of this
chapter several particular solutions:
Т 3 (0, 1,3, 7, 15, 31, ...);
Т 3 (2,5, 11, 23, 47, 95, ...);
if I = 0, then
if I = 2, then
if I = 4, then
if I = -1, then T = (-1,–1,–1,–1, –1,...). // T, = 2" [–1+1] – 1 =
// T, = 2" (0+1] – 1 = 2"
- .
// T, = 2" [2+1] – 1 = 3 × 2" – 1.
T = (4,9, 19, 39, 79, 159, ...); // T, = 2" [4 + 1] – 1= 5 x 2" – 1.
