**For example**

*3 consecutive primes in arithmetic progression*

```
3,5,7 distance 2
151,157,163 distance 6
```

*4 consecutive primes in arithmetic progression*

```
251,257,263,269 distance 6
1741,1747,1753,1753 distance 6
76543,76561,76579,76597 distance 18
```

**Are there five consecutive primes in arithmetic progression?**
