The Progressions of Fuzzy Numbers and Their Features

In this paper a certain progression of fuzzy numbers is introduced that called geometrical- arithmetical progression of fuzzy numbers. We study the features of this kind of progression. We also introduced the geometrical progression of fuzzy numbers and the arithmetical progression of fuzzy numbers through using geometrical-arithmetical progression. If fuzzy numbers change into crisp numbers, then geometrical- arithmetical progression of crisp numbers is obtained which is more general than geometrical and arithmetical progression and in special cases, change into them. There are some numerical examples at the end.
