Answer :

Sure, let's work through each part of the question step-by-step to complete the number patterns.

### Part a)
The pattern "255, 257, [tex]$2 \sqrt{7}$[/tex], 26, 263" is not quite clear or consistent, so we'll skip it for now.

### Part b)
Given sequence: 130, 180, __

1. Notice the difference between the numbers:
- 180 - 130 = 50
2. This suggests the pattern has a common difference of 50.

So, the next number after 180 is:
- 180 + 50 = 230

Completed sequence: 130, 180, 230

### Part c)
Given sequence: 180, 190, __

1. Notice the difference between the numbers:
- 190 - 180 = 10
2. This suggests the pattern has a common difference of 10.

So, the next number after 190 is:
- 190 + 10 = 200

Completed sequence: 180, 190, 200

### Part d)
Given sequence: 200, 400, __, 600, __

1. Notice the difference between the first two numbers:
- 400 - 200 = 200
2. This suggests a common difference of 200.

So, the missing numbers are:
- After 400: 400 + 200 = 600
- After 600: 600 + 200 = 800

Completed sequence: 200, 400, 600, 800

### Part e)
Given sequence: __, 520, __, 540, __

1. Notice the difference between 520 and 540:
- 540 - 520 = 20
2. This suggests a common difference of 20.

The missing numbers are:
- Before 520: 520 - 20 = 500
- After 540: 540 + 20 = 560

Completed sequence: 500, 520, 540, 560

So, the fully completed sequences are:

b) 130, 180, 230

c) 180, 190, 200

d) 200, 400, 600, 800

e) 500, 520, 540, 560
