Describe the similarities and differences between arithmetic and geometric sequences.

1 answer:

6 0

Arithmetic sequence is a sequence with the difference between two consecutive terms constant. The difference is known as the common difference.

Arthmetic Sequence: 2,4,6,8,10,12. The common difference is 2. A pattern of numbers that increase or decrease at a constant amount.

A geometric sequence is a sequence with the ratio between two consecutive terms constant. This ratio is called common ratio.

Geometric Sequence: 2,10,50, 250. 2x5=10 10x5=50 and so on. R=5

A geometric sequence is one where to get from one term to the next you multiply by the same number each time. This number is called the common ration, R.

I hope this helps :)

8y - 9 - ( 4y - 5) = 12y - ( 4 + 5y)

kicyunya [14]

8y-9-4y+5=12y-4-5y

4y-4= 7y-4

Add 4 to both sides

4y=7y. The only answer is 0

Given the diagram, a supplement to ∠ABC could be ∠BDC ∠DAB ∠ADC ∠BAC

Zina [86]

Answer:

Supplement to ∠ABC: ∠DAB acts as a possible supplement

Step-by-step explanation:

There are two approaches to this problem:

1. We can identify an angle by it's measure such that it adds to 180° when added to the m∠ABC

2. As this shape is a quadrilateral, we can tell that two adjacent angles are supplementary to one another, and thus can be identified as the supplement to ∠ABC

For the simplicity, lets take the second method into consideration. We see that ∠ABC is adjacent to the two angles - ∠BCD, ∠BAD. These angles can be rewritten as such: ∠DCB, ∠DAB. And, as we can see from the options, ∠DAB is one of them that may act as a supplement. Shall we check?

The m∠ABC is 110° (degrees) so that it's claimed supplement, ∠DAB should be 70° as to satisfy the first condition of adding to 180°. And, we can see from the diagram that 40° + 30° = 70° so that both "approaches" are met!
