Hey there!!
General formula:
We have:
... (a-b)(a-b)
This could be written as (a-b)²
Hence, the answer is :
<em>... (a-b)² or a²-2ab+b² </em>
<em>Hope my answer helps!</em>
Answer: True

Answer:
B. 97.2
Step-by-step explanation:
The sequence of positive terms is ...
54, 24, 10 2/3, 4 20/27, ...
This sequence has first term 54 and common ratio 24/54 = 4/9. The sum of the infinite series is ...
S = a1/(1 -r) = 54/(1 -4/9) = 54(9/5)
S = 97.2
The sum of the positive terms in the infinite series is 97.2.
