-19
because
4*-5=-20
then -20+1=-19

(7,-35,-34),(-3,15,16), (4,-20, x)

Subtracting ==> last group-2nd last group
==> 4-(-3)=7 /* 1st no in 1st group
==> -20-15= -35 /* 2nd no in 1st group
==> x-16= -34 /* 3rd no in 1st group

On Solving x=-18 So Ans : -18

(7,-35,-34),(-3,15,16), (4,-20, x)

We can also do by adding 1st and 2nd group
==> 7+(-3) = 4
==> -35+15 = -20
==> -34+16 = x ==> -18
So Ans : -18
