Question

The average of 3 consecutive numbers is n. If the next two consecutive numbers are also included, the average of five number will

Answer 1

Answer:

n + 1

Step-by-step explanation:

Consecutive No.s are having difference of 1.

Let the three numbers be x, x+1, x+2    (from the definition of consecutive no.s)

A/q (x + x + 1 + x + 2)/3 = n

which yield the value of x = n - 1    -----(1)

Now the next two no.s will be x + 3, x + 4

taking average,

(x + x + 1 + x + 2 + x + 3 + x + 4)/5 = (5x + 10)/5    

                                                      = x + 2

                                                      = n - 1 + 2     -- -using (1)

                                                     = n + 1

THANKS FOR THE QUESTION !

GIVEN :

=> AVERAGE OF 3 CONSECUTIVE TERMS IS N

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

LET,

THE 1ST NO. :

=> X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

SECOND NO :

=> X + 1

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

THIRD NO :

=> X + 2

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

FORTH NO :

=> X + 3

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

FIFTH NO :

=> X + 4

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

FROM THE GIVEN INFO :

=> X + X + 1 + X + 2 / 3 = N

=> 3X + 3 / 3 = n

=> 3 ( X + 1 ) / 3 = n

=> X + 1 = n

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

CONDITION :

=> 3X + 3 + X + 3 + X + 4 / 5 = ?

=> 5X + 10 / 5 = ?

=> 5 ( X + 2 ) / 5 = ?

=> X + 2

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

SO,

=> THE AVERAGE OF FIVE CONSECUTIVE NO. IS X + 2
