If having radical signs then by methods of mathematical induction which is true
As we learnt in
Steps of Mathematical Induction (Verification step) -
Step 1: Verification step
Actual verification of the proposition of the starting value
- wherein
is divisible by 7
Put n=1, It Satisfies.
and
Steps of Mathematical Induction (Induction Step) -
Step 2: Induction Step
Assuming the proposition to be true for n=k, and proving it is true for value
-
And
Steps of Mathematical Induction (Generalization Step) -
Combine Verification step and Induction step
is true and is true for assuming it is true for
-
which is less than 3 and lesser than 4
For n = k
ak < 7
Sq = an < 7
