Answer:

You add by 5, then 15, then 45 and so on

Step-by-step explanation:

First, you add 5, then you add 15, then you add 45 and so on. You are multiplying 3 and 5 every-time. I don't really know how to explain it but ya.

To get from 3 to 8, add 5. To get from 8 to 23, add 15. You're multiplying by 3 for every number. (I'm super bad at explaining)

Answer: Add the number previously added multiplied by 3;

+3x, where x is the number that was added previously

Step-by-step explanation:

3+5=8. That's the first equation, where 5 is x. Then the next equation, 8+3x=23. 8+15=23. It works for all of the equations, so that's the pattern.

Nata [24]

Step-by-step explanation:

let v is the speed of the wind,

the equation of the speed:

(550 + v ) × 5 = (550 - v) × 6

2750 +5v = 3300 - 6v

11v = 3300 - 2750

11v = 550

v = 550/11

v = 50

therefore, the speed of the wind =

50 mph

Mrs. Wheeler had a bowl of M&M’s sitting on her table. Her daughter Lauren told her that she thought there were 100 M&M’

laiz [17]

There was 33.3% error in her calculation.

Step-by-step explanation:

Approx value thought by Lauren = 100

Exact value counted = 75

Percent error = $\frac{|approx-exact|}{exact}*100$

$Percent\ error=\frac{|100-75|}{75}*100\\\\Percent\ error=\frac{|25|}{75}*100\\\\Percent\ error=\frac{2500}{75}\\\\Percent\ error=33.33\%$

Rounding off to nearest tenth;

Percent error = 33.3%

There was 33.3% error in her calculation.

Taya2010 [7]

N=3:
A) an = 8*3+10 = 34
B) an = 8*3 - 14 = 10 OK
C) an = 16*3+10 = 58
D) an = 16*3 - 38 = 10 OK

n=5:
B) an = 8*5-14 = 26 OK
D) an = 16*5 - 38 = 42

Select the option for "?" that continues the pattern in each question. 2, 7, 26, 101, 400, ?

makvit [3.9K]

Answer:

1595

Step-by-step explanation:

The given sequence is

2, 7, 26, 101, 400, ?

We need to find the missing term in this pattern.

First term is 2.

$a_2=2\times 4-1=8-1=7$

$a_3=7\times 4-2=28-2=26$

$a_4=26\times 4-3=104-3=101$

$a_5=101\times 4-4=404-4=400$

So, the nh term of the sequence is

$a_n=a_(n-1)\times 4-(n-1)$

Substitute n=6,

$a_n=a_(6-1)\times 4-(6-1)$

$a_n=a_(5)\times 4-5$

To find the next term, we need to find the product of 400 and 4 and after that the difference of resultant number and 5.

$a_6=400\times 4-5=1600-5=1595$ .

Therefore, the missing term is 1595.

Anyone know the answer?!

Mumz [18]

Answer: Choice number three is the correct choice: slope = –2, y-int = 4

Explanation: Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line. In this case, number 4 is considered b in this equation which makes it the y-intercept. Remember that the number with the x in an equation such as this is the slope.

Hope this helps, mark brainliest please! :)
