Question

Consider the statement P(n) :" n² +n is divisible by 3" ) prove that P (3) is true​

Answer 1

*Here is your answer:-

We have P(n) = n³ + n is divisible by 3

Hence,

P(3) is the statement 3³ + 3 is divisible by 3

P(3) = 30 which is divisible by 3

P(4) is the statement 4³ + 4 is not divisible by 3

P(4) = 68 which is not divisible by 3

Hence,

P(3) is true while P(4) is not true
