I will try to explain this as best I can. I have a series of numeric progressions (all integers) that I need to be able to calculate in Excel. Here they are:L L/2 L*.75 L (L-4)/3 ? ??
1 +0 +0 +1 +0 +0 +0
2 +1 +1 +2 +0 +0 +0
3 +1 +2 +3 +0 +0 +1
4 +2 +3 +4 +0 +0 +2
5 +2 +3 +5 +0 +1 +3
6 +3 +4 +6 +0 +1 +4
7 +3 +5 +7 +1 +2 +4
8 +4 +6 +8 +1 +3 +5
9 +4 +6 +9 +1 +3 +6
10 +5 +7 +10 +2 +4 +7
11 +5 +8 +11 +2 +4 +8
12 +6 +9 +12 +2 +5 +8
13 +6 +9 +13 +3 +6 +9
14 +7 +10 +14 +3 +6 +10
15 +7 +11 +15 +3 +7 +11
16 +8 +12 +16 +4 +8 +12
17 +8 +12 +17 +4 +8 +12
18 +9 +13 +18 +4 +9 +13
19 +9 +14 +19 +5 +9 +14
20 +10 +15 +20 +5 +10 +15The First column is the level of the progression. The next four columns are progressions I have figured out. The formula for each one is in the header.
It's the last two columns that I can't figure out. How would I express each of those using a formula? I know I can do an Index (Array?), but that seems so clunky.
I suspect the column marked "?" cannot be expressed by a formula because of the +2 at Level 7.
Your input is greatly appreciated.
