Determine the group of numbers for which the following relations hold:
a) The sum of the searched three consecutive even numbers equals 978.
b) The sum of the searched four consecutive odd numbers equals 312.

Correct answer:

a =  324
b =  326
c =  328
x =  75
y =  77
z =  79
w =  81

Step-by-step explanation:

a+(a+2)+(a+4)=978  3a=972  a=3972=324  a=324
x+(x+2)+(x+4)+(x+6)=312  4x=300  x=4300=75  x=75
