The given sequence is 315, 313, 312, 316, 310, 319, ? and we need to find the missing term.

We can observe that the sequence is not following a specific pattern in terms of increasing or decreasing numbers. However, if we look closely, we can see that the difference between consecutive terms is alternating between positive and negative values.

Let's analyze the differences between consecutive terms:

- The difference between 315 and 313 is -2.
- The difference between 313 and 312 is -1.
- The difference between 312 and 316 is 4.
- The difference between 316 and 310 is -6.
- The difference between 310 and 319 is 9.

From the above analysis, we can see that the differences between consecutive terms are alternating between -2, -1, 4, -6, 9.

Now, let's apply the same pattern to find the missing term:

- The difference between 319 and the missing term should be -2.
- Therefore, the missing term should be 319 - 2 = 317.

However, none of the options given in the question match 317.

Let's consider another possibility:

- The difference between 319 and the missing term should be -1.
- Therefore, the missing term should be 319 - 1 = 318.

Option (a) matches 318, so the correct answer is option (a).

Answer: Option (a) - 318
