6/7/18/22
6/7=7/18=18/22
therefore they are in continued proportional......
hey dude here is your answer...... ☺
let 'x' be the number that subtracted from each of the number that we have
i.e is 6-x, 7-x, 18-x, 22-x.
At this point ,you choose to be lazy i . e is
(6-x) (7-x) =(18-x) (22-x)
i.e is
(x-6)(x-7)=(x-18)(x-22)
x(x-7)-6(x-7)=
x(x-22)-18(x-22)
x^2-7x-6x-42=
x^2-22x-18x-396
x^2 gets cancelled.
-x-42=-40x-396
0=-40x-x-396+42
0=-41x-356
354=-41x
x=354/-41
x=-8.6
the number is -8.6
