(E) 18
​

Answer 1

Answer:

18

Step-by-step explanation:

The average of 6 consecutive integers is 18.5

[x+x+1+x+2+x+3+x+4+x+5 ]/6=18.5

[6x +15]=6[18.5]

6x +15=111

6x=96

x = 16

now the 6 consecutive integers are 16,17,18,19,20.21

verage of the first(5)   of these integers   18              [ middle termof 5 terms]
