Let the numbers be : x, x + 1 and x + 2 ~

now, according to given condition :


\qquad \sf  \dashrightarrow \: x + 2(x + 1) = 98 - 3(x + 2)


\qquad \sf  \dashrightarrow \: x + 2x + 2 = 98 - 3x - 6


\qquad \sf  \dashrightarrow \: x + 2x + 3x = 98 - 6 - 2


\qquad \sf  \dashrightarrow \: 6x = 90


\qquad \sf  \dashrightarrow \: x = 90 / 6


\qquad \sf  \dashrightarrow \: x = 15

So, tge required numbers are : 15, 16 and 17
