which sequences are arithmetic? check all that apply. –8.6, –5.0, –1.4, 2.2, 5.8, … 2, –2.2, 2.42, –2.662, 2.9282, … 5, 1, –3, –

In an arithmetic sequence, the next term is found by adding a constant term to each number to arrive at the next number. The common difference can be found by subtracting the first term from the second term.
-8.6, -5.0, -1.4, 2.2, 5.8....the common difference here is 3.6
-8.6 + 3.6 = -5.0
-5.0 + 3.6 = -1.4
1.4 + 3.6 = 2.2
2.2 + 3.6 = 5.8
so this IS an arithmetic sequence.
2,-2.2, 2.42, -2.662, 2.9282...there is no common difference..so this is not an arithmetic sequence
5,1,-3,-7,-11....common difference is -4
5 + (-4) = 1
1 + (-4) = -3
-3 + (-4) = -7
-7 + (-4) = -11
this IS an arithmetic sequence
-3,3,9,15,21...common difference is 6
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15
15 + 6 = 21
this IS an arithmetic sequence
-6.2, -3.1, -1.55, -0.775, -0.3875...this is not an arithmetic sequence
Answer:
The number y decreased by 12.
Step-by-step explanation:
(A) SAS
<u>Explanation:</u>
According to the figure,
One angle of both the triangles are equal
Two sides of both the triangles are equal
If two sides and one angle are equal, then the given triangles are congruent to each other.
The first answer
-40y3/x5
The two bottom graphs demonstrate translations.
<h3>
Which figures demonstrate a translation?</h3>
We will have a translation only if:
- The size of the figure does not change (like in option 1, which we can discard).
- If the "direction" of the figure does not change, like in option 2, where you can see that there is a reflection.
The images where the figures are only moved a little bit are the ones that demonstrate just a translation, and these are the two lower ones.
