The sum of n terms of a geometric sequence with first term "a" and common ratio "r" is given by
You have a=21, r=3, so the sum of 10 terms is
The appropriate choice is the 2nd one:
620,004
Answer:

Answer:
2 rooms
Step-by-step explanation:
To solve this, we need to figure out how many 14/3s go into 28/3. We know this because each room needs 14/3 rolls of wire, and we need to figure out how many rooms the electrician needs to wire with 28/3 rolls.
To find how many 14/3s go into 28/3, we can divide 28/3 by 14/3 to get
(28/3) / (14/3)
= (28/3) * (3/14)
= (28/14)
= 2
2 rooms is our answer
