The correct option is C 2,400
The given sequence is 300, 600, 900, 1200.
Difference between the 1st and the 2nd terms = 600 - 300 = 300
Difference between the 2nd and the 3rd terms = 900 - 600 = 300
Therefore, to find the next term, we have to add 300 to the term.
Hence, the next terms are 1500, 1800, 2100, 2400.
