Then there are infinite possibilities. Use the forumula:
x = First Number in the Sequence
x+1 = Second number in the Sequence
x+2 = Third number in the Sequence
x+n = Last number in the Sequence
(x)+(x+1)+(x+2)+...+(x+n)=100
Solve.
The groupings aren't required. They just help to see where I put the terms x and x+1.
He didn't even specify integers. Why not use rational numbers!
sry, you can only use add, times, divide, and subtract, and the order of numbres has to 123-4-5-6-7-8-9
