22000
The number that's being added in the sequence increases by 2x.
250 * 2 = 500, which is added to 18500 to equal 19000.
500 * 2 = 1000, which is added to 19000 to equal 20000.
1000 * 2 = 2000, which added to 20000 equals 22000.
Let the cosecutive numbers be like this :
2n + 1 , 2n + 2 , 2n + 3 , 2n + 4 , 2n + 5
Odd , Even , Odd , Even , Odd
______________________________
So we have :
(2n+1)+(2n+3)+(2n+5)=(2n+2)+(2n+4) + 39
6n + 9 = 4n + 6 + 39
6n + 9 = 4n + 45
Subtract both sides 9
6n + 9 - 9 = 4n + 45 - 9
6n + 0 = 4n + 36
6n = 4n + 36
Subtract both sides 4n
6n - 4n = 4n - 4n + 36
2n = 0 + 36
2n = 36
Divide both sides by 2
2n ÷ 2 = 36 ÷ 2
<em>n</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em> </em>

So the numbers are :
2(18)+1 , 2(18)+2 , 2(18)+3 , 2(18)+4 , 2(18)+5
36 + 1 , 36 + 2 , 36 + 3 , 36 + 4 , 36 + 5
37 , 38 , 39 , 40 , 41
As u can see the Odd numbers are :
37 , 39 , 41
And we're done ...
Answer:
4/9
Step-by-step explanation:
Answer:
18.8496 units (rounded o1ff to four decimal places)
Step-by-step explanation:
Arc length = 2 × π × r × 
r (radius) = 12 units ÷ 2 = 6 units
Central angle = 180°
For our semicircle, the arc length = 2 × π × 6 × 
= 18.8495559215 units
Or 18.8496 units (rounded o1ff to four decimal places)
