as fast as you can

Answer 1

6)
Let first even no. be x
So second even no. i.e. its consecutive will be x+2
Acc. to ques
x+x+2 =38
2x+2=38
x=18
Therefore nos. are 18 and (18+2)=20

7) Let first odd no. be x
Second no. will be x+2
Third will be x+4
Acc to ques
x+x+2+x+4=51
3x=45
x=15

Therefore nos are
15
(15+2)=17
(15+4)=19

Answer 2

Let two consecutive evennumbers be x, x+2,
According to the given condition,
x+(x+2)=38
2x=36
x=18
,x+2=20
Therefore the numbers are 18,20
