Which is not a factor of 64 2 32. 4 16 6 24. 8 and 8

Step-by-step explanation:

Option d. 1296

Step-by-step explanation:

The given table is x   1     2     3     4     5

                              y   6   36  216   ?   7778

here the table can be represented as

We find an exponential series with the nth term as

Now we have to find the 4th term of this exponential series.

Therefore option d. 1296 is the correct option.
