Question

Insert five arithmetic mean between 3 and 27

Answer 1

Answer:

The answer is 7,11,15,19 and 23

Step-by-step explanation:

Let $a,b,c,d,e$ are the inserted mean between 3 and 27

                 $\Rightarrow 3,a,b,c,d,e,27$ are in A.P.

Now using general term formula $a_n=a+(n-1)d$

                    $27=3+(7-1)d$

                  $\Rightarrow 6d=27-3=24\\\Rightarrow d=4$

Thus $a=3+d=7,b=11,c=15,d=19,e=23$
