Well, the best way to solve this is maybe just to find a pattern, so 2, 3, 1, -2, -3, -1, 2, 3, 1, -2, -3, -1, so we find out that it repeats and the sum is 0 every 6 terms! Now that we know this, We can just find out the last two digits, which are 2 and 3. So 2 + 3 =5, which is our answer

Elza [17]

Answer:

246 physics books

186 biology books

Step-by-step explanation:

1) there are 432 total books

2) there are 60 more physics books than biology books

3) 432 - 60 = 372

4) 372 divided by 2 = 186

5) 432 - 186 = 246

Check:

246 + 186 = 432

246 - 186 = 60

hope this helped :)
