Answer :
Step-by-step explanation:
Given the sum of three consecutive even number is 246.
Let , three consecutive even number are x, x + 2 and x+4.
Now,
x+ ( x+2) + ( x+ 4) = 246
3x + 6 = 246
3 x= 246 – 6 = 240.
3 x = 240÷ 3
= 80
Hence, the three consecutive even number are,
x = 80
x + 2 = 82 ( 80+2)
x + 4 =84 ( 80+4).
Hence this is the answer
