Question

the sum of three consecutive even no. is 210. find the largest of these no.​

Answer 1

Answer:

1st no. : 2n

2nd no.: 2n+2

3rd no.: 2n+4

2n+2n+2+2n+4=210

6n+6=210

6(n+1)=210

n+1=35

n=34

therefore largest no. is 2n+4 = 2*34+4=72

Answer 2

Let,three consecutive even numbers=2n,2n+2,2n+4
=2n+2n+2+2n+4=210
=6n+6=210
=6n=210-6
n=204/6
n=36

Therefore,2n=2(36)
=72
2n+2=2(36)+2
=72+2=74
2n+4=2(36)+4
=72+4=76
Hence three consecutive numbers are 72,74 and 76
