Solution
The correct option is B 420
The given sequence is 60, 120, 180, 240.
Difference between the 1st and the 2nd terms = 120 - 60 = 60
Difference between the 3rd and the 2nd terms = 180 - 120 = 60
Hence, 60 should be added to a term to get the next term.
Therefore, the pattern is 60, 120, 180, 240, 300, 360, 420.
After 7 hours, 420 pizzas would be delivered.
The given sequence is 60, 120, 180, 240.
Difference between the 1st and the 2nd terms = 120 - 60 = 60
Difference between the 3rd and the 2nd terms = 180 - 120 = 60
Hence, 60 should be added to a term to get the next term.
Therefore, the pattern is 60, 120, 180, 240, 300, 360, 420.
After 7 hours, 420 pizzas would be delivered.
