A man climbing a rock at 24 km/hr and downhill 36 km/hr. Determine avg speed?
30,28,25,20,34,28,? what is the next number in the above sequence?
ans=29
3*10=30
4*7=28
3*8=25
4*5=20
3*11=33+1=34
4*7=28
3*9=27+2=29
so like(one digrement and one ingrement valu than adding 1,2,3etc... Ingremented)
Ans:29,
30,28 dif -1
28,25 dif -2
25,20 dif -4
20,34 dif +14
34,28 dif -5
28,? +1=29
29,?+2=31etc
9,18,21,25,20, what is the next number in the above sequence?
ans= 25
bcoz, 3*3=9
3*6=18
3*7=21
5*5=25
5*4=20
so like(3*6 and 3*7 it will be 5*4 and 5*5 mens increment by 1)
2xy/xy= average speed. its very simple
