Answer 2

It looks like you have a sequence of numbers where you are subtracting two consecutive odd numbers from each other, and then adding the next two consecutive odd numbers. Let's break down the pattern:

1. Subtract 97 from 99: 99 - 97 = 2.
2. Add 95 to 2: 2 + 95 = 97.
3. Subtract 93 from 97: 97 - 93 = 4.
4. Add 91 to 4: 4 + 91 = 95.
5. Subtract 89 from 95: 95 - 89 = 6.
6. Add 87 to 6: 6 + 87 = 93.

This pattern continues until you reach:

49. Subtract 5 from 7: 7 - 5 = 2.
50. Add 3 to 2: 2 + 3 = 5.
51. Subtract 1 from 5: 5 - 1 = 4.

So, the final result of the sequence is 4.
