Simple sequence

Continue with this series of numbers: 1792,448, 112, _, _

Correct result:

a4 =  28
a5 =  7


a1=1792 a2=448  k=a1/a2=1792/448=4  a3=a2/k=448/4=112 a4=a3/k=112/4=28a_{1}=1792 \ \\ a_{2}=448 \ \\ \ \\ k=a_{1}/a_{2}=1792/448=4 \ \\ \ \\ a_{3}=a_{2}/k=448/4=112 \ \\ a_{4}=a_{3}/k=112/4=28
