Question

the sum of four consecutive natural number id 158 find the numbers
​

Answer 1

Answer:

They are 38, 39, 40, and 41 .

I do it this way:

== If they were all the same number, they would all be (158/4) = 39.5 .

== Now take away 0.5 from two of them and add it to the other two. Now you have 39, 39, 40, and 40 . Their sum hasn’t changed.

== Take the pair of 39s. Take one away from one of them and add it to one of the 40s . Now you have 38, 39, 40, and 41, and their sum hasn’t changed.
