$\text{0.5, 1, 1.5, 2, 2.5, 3 }$

Explanation:

A question like this is a good introduction to the ideas of sequences.

The numbers of a sequence are called terms, how many terms there are, or which position a particular value occupies is given by "n".

"n" always starts as 1, then 2, 3, 4, ..

For the first term, n=1
For the second term, n = 2
For the third term, n=3.... and so on.

So to find the firs terms in a sequence if you the rule, just substitute, n by 1, 2, 3, 4, .....

$\text{0.5, 1, 1.5, 2, 2.5 , 3}$
