I am using this help-yourself

And have a question regarding
2. Let x = [2 5 1 6].
b. Add 3 to just the odd-index elements

They give the answer as

b = x(1:2:end) + 3

but that makes a new matrix with just two numbers in it.

Like so:
"b =

21 20
"

Is the question or the answer wrong?I am using this help-yourself
