The sum of 4 consecutive numbers is equal to the sum of the next 3 consecutive numbers. find the largest number.

The answer is: The largest number is 15.

Step-by-step explanation:

Let n = the number

n + (n + 1) + (n + 2) + (n + 3) = (n + 4) + (n + 5) + (n + 6)

4n + 6 = 3n + 15

n = 9

Proof:

9 + 10 + 11 + 12 = 19 + 23 = 42

13 + 14 + 15 = 27 + 15 = 42

Hope this helps! Have an Awesome Day!!  :-)

Step-by-step explanation:

Let numbers :

n, n+1, n+2 , n+3

Given:

n + n + 1 + n + 2 + n + 3 = n + 4 + n + 5 + n + 6

4n + 6 = 3n + 15

n = 9

Largest number = n+6 = 15

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
