Question

. A proportion contains the numbers 2,5, and 20. Give TWO numbers that could complete the proportion. Show the proportions on your test grid.

Answer 1

we have the following:

$p=2,5,11,20,32$

the numbers would be 11 and 32, since

$\begin{gathered} p_1=2 \\ p_2=2+3=5 \\ p_3=5+3\cdot2=5+6=11 \\ p_4=11+3\cdot3=11+9=20 \\ p_5=20+3\cdot4=20+12=32 \end{gathered}$
