Skipping Iterations in a For Loop

Hi there, I have a vector
FEM = [-16 16 -18 12 -6 6]
FEM = 1×6
-16 16 -18 12 -6 6
I want to add together (16 + -16), (-18 +_16). (12-18) and (6 + -6)
I have been trying to use a for loop with the code:
for i = 1:6-1
FEM(i+1) + FEM(i)
end
ans = 0
ans = -2
ans = -6
ans = 6
ans = 0
However, from this I get one extra value that I do not want as shown, which is postive 6. What I really want is just [0 -2 -6 0].
I did a quick look up and came across the 'continue' function which should skip an iteration. So I set up the code like this:
for i = 1:6-1
FEM(i+1) + FEM(i)
if i ==3
continue
end
end
ans = 0
ans = -2
ans = -6
ans = 6
ans = 0
but look, I still get the five values instead of the four!
Could somebody help please?
Many thanks in advance!

Basically you have to put the continue before the stuff you want to skip.
FEM = [-16 16 -18 12 -6 6];
for i = 1:6-1
if i ==3
continue
end
FEM(i+1) + FEM(i)
end
ans = 0
ans = -2
ans = 6
ans = 0

Ran in:
FEM = [-16 16 -18 12 -6 6];
n = numel(FEM);
for i = 1:n-3
FEM(i+1) + FEM(i)
end
ans = 0
ans = -2
ans = -6
FEM(end) + FEM(end-1)
ans = 0
