Esitmate:
9 /3 = 3
and
8-4 = 4
so it would be 3x10^4
answer is C
The sequence is incrementing by

Therefore, the sixth number is

Which is 64.
Answer:
Option (3). EF
Step-by-step explanation:
From the figure attached,
Plane defined by EAB can be represented by the face EABF of the square prism also.
Similarly, plane EFG can be represented by the face EFGH of the prism.
Now these sides EABF and EFGH are joining each other at the edge EF of the cuboid.
Therefore, intersection of the given planes is EF.
Option (3) will be the answer.
