Answer:
23
Step-by-step explanation:
1 + 4 = 5 so we get 1 4 5
then 4+5 = 9, 1 4 5 9
5+9 = 14, 1 4 5 9 14
9+14 = 23, so
1 4 5 9 14 23
23 is the 6th number in this sequence
Answer:
Add all of them together. So your answer is
61/10 or 6 and
Step-by-step:
7/5 =1 and 2/5 or 14/10
1/2= 5/10
4/1 or 4= 40/10
14/10 + 5/10 + 40/10 = 61/10
Simplified: 6 and 1/10
Answer:
- 10 quarters
- 20 dimes
- 18 nickels
Step-by-step explanation:
If we add 2 nickels to Sam's coin collection, we can group the coins into groups that contain 1 quarter, 2 dimes, and 2 nickels. Each group is worth $0.55, and all of the coins together will be worth $5.50.
That is, there are $5.50/$0.55 = 10 groups of coins.
Sam has 10 quarters, 20 dimes, and two fewer nickels than 20, so 18 nickels.
The correct answer is A (always).
we have been asked to find the sum of the given geometric series
A geometric sequence has a constant ratio "r" and is given by
The first term of the sequence is
Sum of the sequence is given by the formula
Plug in the values we get
On simplification we get
Hence sum
