First term:  a(1) = 4; common ratio:  r = 2

Then:

a(n) = 4(2)^(n-1)

Check:  Predict the 4th term using this formula:

a(4) = 4(2)^3 = 4(8) = 32  (correct)

Machine A:

60 / 10 = 6 - 10 minute segments per hour

7 x 6 = 42 - parts per hour

42 x 12 = 504 - parts made on Monday

Machine B:

60 / 15 = 4 - 15 minute segments per hour

16 x 4 = 64 - parts per hour

64 x 10 = 640 - parts made on Monday

504 + 640 = 1144 - parts made by the two machines on Monday

Hope this helps!! :)
