Answer 1

${ \huge{\pink{ \mathtt{ answer \: }}}}$

➛Let the three consecutive numbers be X , X+1 , X+2 .

sum of numbers is 51.

therefore

X + X + 1 + X + 2 = 51

3X + 3 = 51

3X = 51 - 3

3X = 48

$X = \frac{48}{3}$

X =. 16

therefore

X + 1 = 16 + 1 = 17

X + 2 = 16 + 2 = 18

➛The three consecutive numbers be 16 , 17 , 18 .

Answer 2

Answer:

$\huge \tt \purple{\underline{LET}}$

Three consecutive integers be x,x+1 and x+2

Three consecutive integers add up to 51.

x+x+1+x+2 = 51

3x+3 = 51

3(x+1) = 51

x+1 = 51/3

x+1 = 17

x = 17-1

x = 16

x = 16

x+1 = 16+1 = 17

x+2 = 16+2 = 18

• The three consecutive integers are 16,17 and 18.
