The given sequence is constituted by respectively multiplying  4, adding 4, dividing 4 and subtracting 4 to a given term to obtain the next term, and threafter repeating the operations .
Thus,

First term = 5
Second term = 5*4=20
Third term = 20+4 = 24
Fourth term = 24/4= 6
Fifth term =  6-4= 2
Sixth term = 2*4=8
Seventh term = 8+4 = 12

Consequently, the next term (seventh term) of the given sequence must be 12.
