Answer:

7, 8,9

Step-by-step explanation:

let us consider "y" as the variable

(y X 2) + [(y+1 ) X 3)] + [(y+2) X 4] =74

2y + 3y+3 + 4y + 8 =74

9y + 11 = 74

9y = 74-11

9y = 63

y = 63/9

y = 7

y=7

7+1=8

7+2=9

\bf \underline{ \underline{\maltese\:Given} }

Three consecutive integers are such that when they are taken in increasing order and multiplied by 2, 3 and 4 respectively, they add up to 74.

\bf \underline{\underline{\maltese\: To \: find }}

 \sf \implies Three  \: consecutive  \: numbers =  \: ?

\bf \underline{\underline{\maltese\: Solution }}

 \sf \implies Let  \: the  \: first \:  integer  \: be \:  x

 \sf \implies Then,  Second  \: integer = (x+1)

 \sf \implies Third  \: integer = (x+2)

 \bf \underline{According \:  to \:  question},

 \sf  Our  \: equation  \: will  \: be :

 \bf\implies  x \times 2 + 3(x + 1) + 4(x + 2) = 74

 \sf\implies  2x  + 3x + 3+ 4x + 8 = 74

 \sf Taking \:  the  \: like \:  terms,

 \sf\implies  2x  + 3x + 4x +  3+ 8 = 74

 \sf\implies  9x +  3+ 8 = 74

 \sf\implies  9x +  11 = 74

 \sf\implies  9x  =  74 - 11

 \sf\implies  9x  =  63

 \sf\implies x  =   \dfrac{63}{9}

 \sf\implies x  = 7

 \sf  Now, these  \: numbers \:  are :

 \sf\implies First \:  number = \bf x  = 7

 \sf\implies Second \:  number = \bf  (x+1)  = (7+1) = 8

 \sf\implies Third  \: number  = \bf  (x+2)  = (7+2) = 9

━━━━━━━━━━━━━━━━━━━━━━━━━━━

\bf \underline{\underline{\maltese\: Verification  }}

 \bf\implies  x \times 2 + 3(x + 1) + 4(x + 2) = 74

 \sf\implies  7 \times 2 + 3 \times 8 + 4 \times 9

 \sf\implies  14+ 24+ 36

 \sf\implies  74

 \bf Hence \:  verified  \: !
