εIf P(n) = 2+ 4 + 6+....+ 2n, n N, then P(k) = k(k+1) + 2
=> P(k+1) = (k+1)(k + 2) + 2 for all k belongs to N. So we can conclude that P(n) = n(n+1)+2 for
a. all n belonging to N
b.n>1
c.n>2
d. nothing can be said
Ans: D
Why??
1oh yes...but then one of the options shd be NOT...may b printing mistake in the Q
Another similar type QLet P(n) be a statement and let P(n) => P(n+1) where n is natural number, then P(n) is true
. for all n
b.for all n>1
c.for all n>m
d.Nothin can b said
9c if its given p(m) is true
so ans mostly d
quite ambiguous
dont bother abt these wrong Qs and waste ur time :P
