Answer 2

It seems like you're presenting a sequence of arithmetic operations. The pattern appears to be alternating between subtracting 2 and adding 2 to consecutive odd numbers. Let's break it down:

Starting with 899: 899 - 897 = 2 895 - 893 = 2 ... 807 - 805 = 2 803 - 801 = 2

If we sum up all these individual results, we have:

2 + 2 + ... + 2

Since there are 50 pairs of numbers, and each pair contributes 2 to the sum, the total sum is:

50 * 2 = 100

So, the value of the expression is 100.
