MATLAB: Form a row vector

matrix manipulation

I have to form a row vector x=[5 6 16 17 27 28 38 39….] till the total number of elements become 'n' where 'n' is entered by the user. Say, I enter n=4 so my x=[5 6 16 17]
basically what I want is that if I have two numbers say, X and Y and I wish to give some increment to these numbers to form a row matrix containing 'n' elements. Say, increment is 3 and n is 6 A=[X Y X+3 Y+3 X+6 Y+6]

First, get all the X+... and Y+... separately and get them into the correct order then (Activate the commented % to stop the output as it's only for educational reasons here):
>> inc=11;X=5;Y=6;
>> N=3;
>> Z=[X+(0:N-1)*inc;Y+(0:N-1)*inc] %;  %first row: X+..., second row: Y+...
Z =
       5    16    27
       6    17    28
>> Z(:)'
ans =
       5     6    16    17    27    28
