Missing number in the series 9, ____, 6561, 43046721 is: 81 25 62 31 18 9. one number is 2 more than 3 times another. their sum
Nadusha1986 [10]

Alright, lets get started.

Missing number fom the series :  9, ..... , 6561, 43046721

43046721 is square of its previous number 6561, means

6561^2 = 43046721

It means the missing number will be square of its previous number

Means 9^2 = 81, so missing number is 81.   :    Answer

Next : one number is 2 more than 3 times another. their sum is 22. find the numbers.

Suppose one number is x and second number is y

As per given equation, x = 3y + 2  ......equation (1)

Their sum is 22  means,  x+y = 22 .......equation (2)

Putting the value of x from equation1 into equation 2

3y + 2 + y = 22

4y + 2 = 22

Subtracting 2 in both sides

4y + 2 - 2 = 22 - 2

4y = 20

y = 5

x = 22 - y = 22 - 5 = 17

Means numbers are 17 and 5.   : Answer


Next : the missing number in the series 1, 4, 27,____, 3125 is

1 could be written as 1

4 could be written as 2^2

27 could be written as 3^3

So , next number would be 4^4

4^4 = 256

Next one is 5^5 = 3125

So, the missing number is 256   :    Answer


Next : the next number in the series 3, 4, 6, 7, 9, 10 is

After 3,4 (5) is mising, 6, 7 (8) is missing, 9, 10 (11) will be missing

So, next number will be 12.   : Answer



Next : a farmer is planting a straight row of crops with 3 feet between each plant. if 23 are planted, what is the distance between the first and last plant?

Between 2 plants, the distance is = 3 * (2-1) = 3

Between 3 plants, the distance is = 3 * (3-1) = 6

So, between 23 plants, the distance is = 3 * (23-1) = 3 * 22 = 66

hene the distance between first and last plant woule be 66 feet.   :   Answer

the sum of two consecutive even integers is greater than or equal to 34 what are the smallest possible integers?
DedPeter [7]

n, n + 2 - two consecutive even integers

the sum of two consecutive even integers is greater than or equal to 34

n + (n + 2) ≥ 34

n + n + 2 ≥ 34

2n + 2 ≥ 34       <em>subtract 2 from both sides</em>

2n ≥ 32      <em>divide both sides by 2</em>

n ≥ 16

<h3>Answer: The smallest possible integers is equal 16.</h3>
