Options

A. 1020
B. 1135
C. 1285
D. None of these

Explanation

To find the missing number in the series 11, 26, 58, 124, 258, 528, we will analyze the pattern in the series step by step.

### Step 1: Identify the pattern
We will look at how each number relates to the previous one.

- From 11 to 26:
- Multiply 11 by 2: \(11 \times 2 = 22\)
- Then add 4: \(22 + 4 = 26\)

- From 26 to 58:
- Multiply 26 by 2: \(26 \times 2 = 52\)
- Then add 6: \(52 + 6 = 58\)

- From 58 to 124:
- Multiply 58 by 2: \(58 \times 2 = 116\)
- Then add 8: \(116 + 8 = 124\)

- From 124 to 258:
- Multiply 124 by 2: \(124 \times 2 = 248\)
- Then add 10: \(248 + 10 = 258\)

- From 258 to 528:
- Multiply 258 by 2: \(258 \times 2 = 516\)
- Then add 12: \(516 + 12 = 528\)

### Step 2: Determine the next number
Now we will apply the same pattern to find the next number after 528.

- Multiply 528 by 2:
\[ 528 \times 2 = 1056 \]
- Then add 14:
\[ 1056 + 14 = 1070 \]

### Conclusion
The next number in the series is **1070**.
