From an analysis of the rise and fall off time of solar cycles 4 to 22, a recurrence tendency of 7 cycles is observed in the rise time and, apparently, of 9 cycles in the fall off time. The envelope of these times presents a decreasing amplitude of oscillation. According to this behavior, the rise and fall length of future solar cycles until cycle 25 can be inferred qualitatively. These values are compared to with those obtained with a multiple regression method showing a good agreement.
