vectors addition

[ptc-4892444]

Hello together,

I have a problem which I can not solve alone. It is nothing major but I can´t sind an answer. Maybe someone can help me.

I am working with Mathcad Prime 2.0.

I got a vector with 42 Numbers, now I want to add the first number to the last number and the second with the penultimate and so on.

I tried something out but it didn´t worked really well. Maybe someone can help me please.

Thanks

You don't need the index k.

Your last line should look like this: r[l:=abs(d[l)+abs(d[43-l)

Note: The "l" is a lowercase "L".
