The elements in the set M are continuous positive integers, and | m | ≥ 2. The sum of the elements in M is 2002. There are several such sets M

The elements in the set M are continuous positive integers, and | m | ≥ 2. The sum of the elements in M is 2002. There are several such sets M

M is a set, what does | m | denote? Is it the number of elements of set M? According to this solution, let m be the smallest element in M, and there are k elements in total, then km + [K (k-1)] / 2 = 2002, and K (2m + K-1) = 4004. Since (2m + k-1) - k = 2m-1 is odd, 4004 is decomposed into 4 * 1

Is there such a positive integer m that the fractional equation 2 / X - [(x-m) / (x ^ 2-x)] = 1 + 1 / (x-1) about X has no real solution? If it exists, find the value of M. if it does not exist, explain the reason

2/x-[(x-m)/(x^2-x)]=1+1/(x-1)
x^2-x+2-m=0
According to the discriminant: B & sup2; - 4ac
