The sum of three consecutive numbers is 498.what is the 3rd number
marshall27 [118]

Answer:

Denote 3 consecutive numbers as: (n-1), n, (n+1)

=> n - 1 + n + n + 1 = 498

=> 3*n = 498

=> n = 166

=> n + 1 = 166 + 1 = 167

=> 3rd number is 167

The Mean of 5 numbers is 20 the median is 23 what might the number be
valentina_108 [34]

13, 15, 23, 24, 25

Median is 23 because it comes in middle of five numbers

To find the mean, add up the values in the data set and then divide by the number of values that you added

if we sum these numbers we get 100 then divide it by 5 we get

100/5 = 20

Find the sum of the first 50 terms.<br> -6,-2,2,6
Veseljchak [2.6K]

Answer:

4600

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4

This indicates the sequence is arithmetic with sum to n terms

S_{n} = \frac{n}{2} [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

Here a₁ = - 6 and d = 4 , then

S_{50} = \frac{50}{2} [ (2 × - 6) + (49 × 4) ]

     = 25(- 12 + 196)

     = 25 × 184

     = 4600

The sides of one right triangle are 6, 8 and 10. The sides of another right triangle are 10, 24 and 26. Determine if the triangl
Arlecino [84]
Corresponding sides are 6,10 8,24 10,26 now my question is these numbers out side the triangle or in side cuz if so in side u need the out side numbers to determine if is similar or not add the out side numbers then subtract it from 180 to get ur 3rd missing number in the triangle now if there more than 2 triangle wich of (how ever many u got) of triangles find the ones in wich have to the same numbers sooo for example if there's 3 triangles one big one medium and one large find the corresponding sides of the 3 triangles is step one then there should be a missing number in all three triangles add the to first in the triangle then subtract it from 180 to get the missing number then you can determine if the correspond or not then you need to take that outside measures that correspond and put them in the fraction then you will simplify it with the greatest number that can divide the two numbers in the fraction
