Answer:

Step-by-step explanation:
Since the sequence is geometric (it multiplies the previous number each time). The nth term sequence would be 
Because the sequence multiplies by 3 each time, The base number in that equation would be
.
So
of the equation would be:
.
Compare the 2 equations:
4, 12, 36
3, 9 ,27
The difference between the 2 equations is: 1, 3, 9 which itself is a geometric sequence so the nth term of this new equation is:
.
Combine these 2 equations together and you get:
.
Given:
The product of
and
greater than 5.
To find:
By how much the product of
and
greater than 5.
Solution:
First we need to find the product of
and
.




Now subtract 5 from the product.

Therefore, the product of
and
is 9.85 greater than 5.
