Find the missing termG, K, M, ?, S

The missing term in the sequence G, K, M, ?, S is P.

Here's the step by step solution:

1. Convert each letter to its corresponding numerical value in the alphabet. G is 7, K is 11, M is 13, and S is 19.

2. Look at the differences between the numbers. The difference between 11 and 7 is 4. The difference between 13 and 11 is 2.

3. If we follow this pattern, the next difference should be 4 again (alternating between 4 and 2). So, add 4 to the numerical value of M (13), which gives us 17.

4. Convert 17 back to its corresponding letter in the alphabet, which is P.

So, the missing term is P.
