Step-by-step explanation:
This is an arithmetic progression. In this case, we have been given the first term and the common difference. The formula to find the nth term will be:
= a + (n - 1)d.
Therefore, the first four terms are:
1st term = 300
2nd term = a + (n-1)d = a + (2-1)d = a + d = 300 + 50 = 350
3rd term = a + (n-1)d = a + (3-1)d = a + 2d = 300 + 2(50) = 300 + 100 = 400
4th term = a + (n-1)d = a + (4-1)d = a + 3d = 300 + 3(50) = 300 + 150 = 450
