Ihonestly don’t understand this at all can you ?

A. the first box is 7 
    the second box is 2
    the third box is 100 
    the fourth box is 6.5
    RULE: times 3 + 2
b. the first box is 45/2
    the second box is -0.75
    the third box is 0
    the fourth box is 2.75 
    RULE: times 5/2
c. the first box is 1 1/2
    the second box is 6
    the third box is -4
    the fourth box is -1.75
    RULE: times half add one
