Answer:
1/5
Step-by-step explanation:
Arithmetic sequence: must have a constant common difference.
3/20-1/10=(3-2)/20=1/20
5/30-3/20=(10-9)/60=1/60
Difference is not constant, so no.
Geometric sequence: must have a common ratio
30/20 / (1/10) = 15
5/30 / (3/20) = 100/90 = 10/9
ratio is not constant, so no.
The answer is (c) neither geometric nor arithmetic
Answer:
k = 3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
Step 2: Add 79 to both sides.
Step 3: Divide both sides by 2.
Add -4x and 3x to get -x. then divide -1 on both sides. x=-2
Answer:
The answer is d
Step-by-step explanation: A is starting with a positive so is B so that leaves you C and D, c starts with negative number and still ends in a negative number because 15-10=5 leaving that as still the negative number so D would be the correct answer. Edge 2020
