Question

5 4 3 =18
3 3 5=65
3 8 9 =?​

Answer 1

Answer:

3 ,8, 9 = 68

Step-by-step explanation:

To find the solution for this series

5,3,4 =18 ; 3,5,3=65; 9,8,3=?

So, take  the  first series in the format:-

n₁²-(n₂+n₃)                ------->(equation  1)

substitute the value of first series in it to get R.H.S value

                    = 5²-(3+4)

                    = 25-7

                    =18

so like this only to substitute for the second series to change or alter equation  slightly for substitution,

n₁⁴- (n₂+n₃) -1               ------->(equation 2)

substitute the value for equation 2 from second series;

                     =3⁴-(5+3)-1

                     =81-(15)-1

                     =65

for the third series we have to alter the equation like

n²-(n₂+n₃)-2

substitute the value in it,

                   =9²-(8+3)-2

                   =81-(11)-2

                   =68

Hence the value for the series 9, 8, 3 is 68
