Answer:d
Step-by-step explanation:
Clearly from observation option D is the exponential sequence
256,64,16,4 is decreasing exponential function
[tex]\Rightarrow \frac{256}{64}=\frac{4^4}{4^3}=4[/tex]
[tex]\Rightarrow \frac{64}{16}=4[/tex]
for other option they simply follow an AP
2,6,10,14,18
common difference d=4
