              |                              |                             |                               |
              |------------+ 5---------|-----------+ 5---------|------------+ 5---------|

ANSWER 32
$\frac{5}{16}, \frac{5}{4}, 5, 20, ?$
The next term is 80. 
Each term is multiplied by 4. 
$\frac{5}{16}*4=\frac{5}{4}$
$\frac{5}{4}*4=5$
5 × 4 = 20
20 × 4 = 80
