122, 123, 124, 125, 126. The only way for the mean of 5 consecutive numbers to be 124 is if the median is also 124.
125, 126 and 127.
The numbers are 125 and 126.
62 and 63
That doesn't work. The number has to be divisible by three. Any three consecutive numbers add up to a multiple of three.
121 123 125 127
124 + 125 + 126 = 375
124, 125 and 126
560.66 recurring is the average.
It isn't possible to solve that. The sum of three consecutive integers is always a multiple of 3 (try it out with a few small numbers); 125 is not a multiple of 3, ergo, the problem has no solution.
The average is the sum of the numbers in the set divided by the number of numbers in the set. In this case it is (125+143+134)/3=134.
The numbers are 122, 123, 124 as well as 121, 123, 125.
