Answer:
B and D
Step-by-step explanation:
Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
an = ar^(n-1)
d) 1/3, 2/3, 4/3, 8/3, 16/3, . . . .
1/3 * 2 = 2/3
2/3 * 2 = 4/3
4/3 * 2 = 8/3
where r = 2, constant multiplier is 2. //Answer
b) 320, 80, 20, 5, 1.25, . . . . .
320 * 1/4 = 80
80 * 1/4 = 20
20 * 1/4 = 5
r = 1/4 //Answer
Answer: B and D

Answer:
i dont understand
Step-by-step explanation:
Given:
Principal = $50
Rate of simple interest = 6%
Time = 3 years
To find:
The amount after 3 years.
Solution:
Formula for simple interest:
Where, P is principal, r is the rate of interest in percentage and t is the number of years.
Putting in the above formula, we get
Formula for amount is:
Where, P is principal and I is the simple interest.
Putting , we get
Therefore, the correct option is B.
