Answer:
Step-by-step explanation:
80,120,160.....
This is an arithmetic sequence
common difference (d) = 2nd term - 1st term 
                                       = 120 - 80 = 40
first term (a) = 80
nth term = a + (n-1)d
               = 80 + (n-1)*40
               = 80 + 40n -40
               = 40 + 40n
