Question

In using mathematical induction to prove

Answer 1

true I am sure ;)

Answer 2

replace the n in the formula by k+1 then simplify

Answer 3

No - i think that's P k not P k+1

Answer 4

every n is replaced by k which means its P k

Answer 5

P k+1 would be [k(2k -1)(2k + 1)] / 3 + (2(k +1) - 1))^2

which you would need to simplify

the answer is false

Answer 6

the last term is the (k+1)th term where n is replaced by (k+1) in the nth term (2n -1)^2
