Help please, I'll give brainliest :< to whoever can answer and give the solutions​

1.  -2, -1, 0, 1, 2.

Solution:

Let x be the middle term of this sequence of 5 terms.

Then the sequence is x-2, x-1, x, x+1, x+2.

The sum of the terms is (x-2) + (x-1) + x + (x+1) + (x+2) = 5x.

Thus 5x = 0.

It gives x = 0.

So the sequence is  -2, -1, 0, 1, 2.

2. 24

Solution:

Let x be age of Iori and

2x would then be Karen's age (twice as old as Iori), then,

(x + 2x) + 6* = 42 ( 6 because three years times two = 6 (of course they both get older three years from now))

3x +  6 = 42

3x = 42 - 6

3x = 36

x = 36/3

x = 12

Substituting, we'll have;

Iori = 12

karen = 24

3. 10 weeks

Solution:

4,000÷400=10

for making sure: 400×10=4,000

Mark me brainliest if this helps :)

3. Fifteen weeks

Step-by-step explanation:

well if you subtract the 4000 from the 10000 you get 6000 and then divide 6000 by the 400 and you get 15

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
