Direction: Which of the following will be the next term in the series given below?77, 75, 79, 78, 81, 81, ?

The pattern in the series is as follows:

77, 75, 79, 78, 81, 81, ?

If we look closely, we can see that the series alternates between subtracting 2, adding 4, subtracting 1, adding 3, and adding 0.

77 - 2 = 75 75 + 4 = 79 79 - 1 = 78 78 + 3 = 81 81 + 0 = 81

Following this pattern, the next operation should be subtracting 2.

So, 81 - 2 = 79

Therefore, the next term in the series is 79.
