How would i generate a secuence of N amount of numbers starting at -4 and going up in steps of 2?

Those sequence codes work if i have an end value of the secuence but i need the sequence to contain n amount of elements regardless of the last value

Those sequences work with variables as end values as demonstrated in the answer by Benni.

You can create sequences with the colon operator (:), for exapmle
v = [4:2:100];
creates v = [4, 6, 8, ... , 100] with values starting at 4, an increment of 2 and stop value 100.
For N numbers starting at -4 and an increment of 2, you have to calculate the stop value:
N = 10;
start_val = -4;
inc = 2;
stop_val = (N-1)*inc + start_val;
v = [start_val:inc:stop_val];
