Answer: Aₙ = Aₙ₋₁*3; where A₀ = 2.5
Step-by-step explanation:
Let's try with some known sequences:
Arithmetic.
The difference between consecutive terms is constant:
7.5 - 2.5 = 5
22.5 - 7.5 = 15
We can already see that it is not an arithmetic sequence.
Geometric:
The ratio between consecutive terms is constant.
7.5/2.5 = 3
22.5/7.5 = 3
67.5/22.5 = 3
...
We can already see that this is a geometric sequence.
Then we can write the n-th term as:
Aₙ = Aₙ₋₁*3, where A₀ = 2.5
Answer:
8, -8 and 1
Step-by-step explanation:
Answer:
Note: When you add this to your homework, paraphrase.
Graphs are used to plot down information, find differences between numbers, make a visual for numbers, make patterns, and see how many of something there are.
Answer:
1, 4 complementary
2, 3 supplementary
5, 6 neither
Step-by-step explanation:
complementary angles are angles in which the sum of both is equal to 90 degrees. supplementary angles are angles in which their sum is equal to 180 degrees.
