Question

media aritmetică a cinci numere naturale consecutive este 12 Află numerele​

Answer 1

[a + b+c+d+e]/5=12

=>a+b+c+d+e=5×12

=>a+b+c+d+e=60

=>b=a+1;c=a+2; d=a+3; e=a+4

=>a+[a+1]+[a+2]+[a+3]+[a+4]=60

=>5a=60-1-2-3-4

=>5a=50

=>a=50/5

=>a=10

=>b=a+1

=>b=10+1

=>b=11

=>c=12;d=13;e=14
