Answer:
The area should be 170
Step-by-step explanation:
L× W =70×10=170
Answer:
The required recursive formula is:

Step-by-step explanation:
We are given a geometric sequence as:
6,-18,54,-162,.....
Clearly after looking at different terms of the sequence we could observe that the sequence is an geometric progression (G.P.) with common ratio= -3 denoted by r.
Let
represents the nth term of the sequence.
This means that:

As the common ratio is -3.
so,

Hence, the required recursive formula for the geometric sequence is:

Multiply straight across
5/1 * 3/4 = 15/4
now change it into a mixed number
3 3/4
