Problem 5.3. Define a1 = 2, a2 = 4 and an =
for all natural numbers n. Use the Principle of Complete Induction (PCI).
Hint. Follow the steps of PCI. You need to verify an = 2" when n = 1 and n =
The statement you (should) prove is a, = 2". Also note that one can equivalently write
= 5an – 6an-1 for all n > 2 (instead of an
2 individually.
: 5ал-1 — 6ал-2 for all n > 3).
Expert Solution
Step 1
Introduction:
Mathematical induction is a mathematical technique for proving that a statement, formula, or theorem is true for all natural numbers.
As stated below, the technique consists of two steps to prove a statement.
Step 1 (Base step) establishes the truth of a statement for the initial value.
Step 2 (Inductive step) establishes that if a statement is true for the nth iteration (or number n), it is also true for the th iteration (or number ).
