Consider an infinite sequence of balls: b1,b2,b3,b_1, b_2, b_3, \cdots . Each ball is either red or green. For this, we define the following predicates, where the domain of variable ii is the set of all positive integers (Z+Z^+

):

R(i)R(i) \equiv "ball bib_i

is red".

G(i)G(i) \equiv "ball bib_i

is green".

Assume that i(R(i)G(i+1))T\forall i (R(i) \to G(i+1)) \equiv T, what can you conclude if it is known that ball b1b_1 is red?
