Answer:
1/4,1/2,1,2
Step-by-step explanation:
Use the following formula below:
r=n-k√an(n is lowercase)
Over ak(k is lowercase)
~r=4-1√a4(4 is lowercase)
Over a1(1 is lowercase)
r=3√2
Over 1/4
r=3√8
r=2
Multiply the common difference to the first given extreme to obtain the missing means.
1/4×2=1/2
1/2×2=1
1×2=2
