Question

Media aritmetica a cinci numere naturale consecutive este 834.Aflati cele cinci numere.

Answer 1

$\frac{a+b+c+d+e}{5}$ = 834
b=a+1
c=a+2
d=a+3
e=a+4
$\frac{a+a+1+a+2+a+3+a+4}{5}$ = 834 
5a + 10 = 834 * 5
5a + 10 = 4170
5a = 4160
a = 4160 : 5
a = 832
b = 832 + 1 = 833
c = 832 + 2 = 834
d = 832 + 3 = 835
e = 832 + 4 = 836

Answer 2

Ma=834
(a+a+1+a+2+a+3+a+4)/5=834
(5a+10)/5=834
5a+10=834x5
5a+10=4170
5a=4170-10=4160
a=4160:5=832
a+1=833
a+2=834
a+3=835
a+4=836
