You want to make the denominator of the fractions to be equal to each other.

(2/n+8)+(4/n+1) multiply n+1 by n+8, and multiply n+8 by n+1

(4n+32/n^2+8)+(2n+2/n^2+8) Now that the denominators are equal we can solve the numinator by adding like terms.
4n+2n=6n, 32+2=34

Your final answer is 2(3n+17)/n^2+8

Answer: inductive argument.

Deductive argument is a logical argument in which a conclusion is made upon the given premises which are assumed to be true.

inductive argument works on the basis of a series of observation and then bring it to frame a certain conclusion.

Here, Flanagans are considering the observation they made by previous children (i.e. they are athletically gifted) and applying the same on the new one by saying "youngest child is bound to be athletically gifted as well.".

So it is of-course an inductive argument.
