So in this question, we've been given a scenario where we are dealing with 2n plus 1, which is raised to the power of 2, saying this is an integer.
00:12
So before we actually answer this question, we need to appreciate what a proposition or a statement is.
00:18
So this is a sentence that is known to be true or not to be false, but not both.
00:24
So if we don't know if a sentence is true or false, then the sentence is not propositional.
00:30
Is it a statement? so if we look at p, p represents the propositional function with respect to d if for each x e d we are looking at px as a proposition.
00:48
This d right here is representing the domain of discourse.
00:53
Now going back to what we've been given for every integer and this right here is an odd integer.
01:03
This statement that we just say it will be known to be true or false...
