If `P(n)` is the statement `n^3+n` is divisible 3 is the statement `P(3)` true ? Is the statement `P(4)` true?

Text Solution

Verified by Experts

Given as `P (n) = n^3 + n`
is divisible by 3
Therefore,` P (3) = 3^3 + 3 `
= `27 + 3 = 30`
`P (3) = 30,`
So it is divisible by 3
Then, let’s check with P (4)
`P (4) = 4^3 + 4 = 64 + 4 ...
