Problem 26E
Suppose that P(n) is a propositional function. Determine for which nonnegative integers n the statement P (n) must be true if
a) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n + 2) is true.
b) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n + 3) is true.
c) P(0) and P(1) are true; for all nonnegative integers n. if P(n) and P(n + 1) are true, then P(u + 2) is true.
d) P(0) is true; for all nonnegative integers n, if P(n) is true, then P(n + 2) and P(n + 3) are true.
