Options

A. 25
B. 30
C. 27
D. 34

Answer

To find the next number in the series 16, 18, 22, 24, 28, 30, we can follow these steps:

### Step 1: Identify the pattern in the series
Let's write down the series:
16, 18, 22, 24, 28, 30.

### Step 2: Calculate the differences between consecutive numbers
- From 16 to 18: 18 - 16 = 2
- From 18 to 22: 22 - 18 = 4
- From 22 to 24: 24 - 22 = 2
- From 24 to 28: 28 - 24 = 4
- From 28 to 30: 30 - 28 = 2

### Step 3: Observe the pattern in the differences
The differences are:
- 2, 4, 2, 4, 2

We can see that the differences alternate between adding 2 and adding 4.

### Step 4: Determine the next difference
Following the established pattern, the next difference after the last one (which was +2) should be +4.

### Step 5: Calculate the next number
Now, we add 4 to the last number in the series:
30 + 4 = 34

### Conclusion
The next number in the series is **34**.
