hi there,
I have to create a formula in excel that will list 601 evenly spaced points in between the numbers (-2,10) and i have no clue how to go about this. Thanks for all the help!

What would be your answer if it was 3 evenly spaced points?

for 1 evenly spaced point between -2 & 10

$\dfrac{10 - (-2)}{2}$ = 6

-2, -2+6*1, 10
or
-2, 4, 10

--
for 2 evenly spaced points

$\dfrac{10 - (-2)}{2+1}$ = 4

-2, -2+4*1, -2+4*2, 10
or
-2, 2, 6, 10

--
for 11 evenly spaced points

$\dfrac{10 - (-2)}{11 +1 }$ = 1

-2, -2+1*1, -2+1*2, -2+1*3, ... , 10
or
-2, -1, 0, 1, 2, 3, 4, ...

--
for 99 evenly spaced points

$\dfrac{10 - (-2)}{99 +1 }$ = 0.12

-2, -2+0.12*1, -2+0.12*2, -2+0.12*3, ... , 10
or
-2, -1.88, -1.76, -1.64, ...

--

There is a pattern.

For 601 evenly spaced points between -2 and 10, well, that is left as as exercise for the reader.

4. put -2 in A1

put 10 in A603

put =A1+($A$603-$A$1)/602 in A2 and fill down to A602

5. Each cell should grow by $0.0199335548172757$

If you make that 599 instead, you get 12/600 = .02; more manageable...
Anyhow, my point is: WHY list 599 numbers in between -2 and 12:
[-2] - 1.98, - 1.96, ...... 11.96, 11.98 [12] ?
WHAT is the purpose?
Isn't it enough for you to know that if 2 post holes are dug, ONE post
in between will create TWO sections? Or n posts will create n+1 sections?
