Simulink: select element from a vector in relation with the current time

I'm new to Simulink I have a long vector and I want to select one single element for every time (sampled every five seconds).

For example if I have a vector V = [100 2 192 18 5 ...] I want to select at times t=1, t=2, t=3, t=4, t=5 the element V[1] = 100, at time t=6, t=7, 7=8, t=9, t=10 the element V[6] = 2, and so on.

Is there a block or a set of block to do so? And what options should I use?
