Answer:

Write an equation, in function of x, to represent the situation.

Explanation:

Assuming the smaller number is x, the larger x + 2, since odd numbers come at intervals of two numbers (even, odd, even, odd, etc.)

#x + x + 2 = 304#

#2x = 302#

#x = 151#

The numbers are 151 and 153.

Practice exercises:

  1. The sum of three consecutive numbers is 171. Find the three numbers.

  2. The sum of four consecutive even numbers is 356. Find the four numbers.

Good luck!

Answer:

#151 and 153#

Explanation:

Always remember that consecutive integers differ in the value of #color(orange)(2#:

So,Let the first number#=color(red)(x#

Then,second number=#=color(red)(x+2#

Substitute the values into the equation:

#rarrcolor(blue)((x)+(x+2)=304#

Remove the brackets:

#rarrx+x+2=304#

#rarr2x+2=304#

#rarr2x=304-2#

#rarr2x=302#

#color(green)(rArrx=302/2=151#

So,

#color(green)(x=151 , x+2=151+2=153#
