A gap opening penalty for any gap (g) and a gap extension penalty for each element in the gap (r) are most often used, to give a total gap score wx, according to the equation ______

A gap opening penalty for any gap (g) and a gap extension penalty for each element in the gap (r) are most often used, to give a total gap score wx, according to the equation ______ Correct Answer wx = g + rx

wx = g + rx is the equation where x is the length of the gap. in some formulations of the gap penalty, the equation wx = g + r (x – 1) is used. Thus, the gap extension penalty is not added to the gap opening penalty until the gap size is 2.
