Question

the sum of three consecutive natural number is 48.find out the other number

Answer 1

Answer:

Dividing #48/3=16#

Explanation:

This is the middle number. The others are one less and one more:

#15,16,17#

In addition, there is another way to solve this.

For instance, you know that the sum of three numbers must add to be 48. Also, you know that they are consecutive.

Thus, you can represent the value of the least number with #x#.

Moreover, since they are consecutive numbers you can represent the value of the next number with #x+1#.

Now, for the third number you simply add 2 (#x+2#).

The equation would look something like this:

#(x)+(x+1)+(x+2)=48#

#3x+3=48#

#cancel (+3)# on both sides

#3x=45# divide by 3

#x=15#

Substitute for the other values when #x=15#:

#x+1# #-># #15+1=16#

#x+2# #-># #15+2=17#

Finally, the three answers are #15, 16 and 17.#
