Q. Predict the next number
2,20,10,100,50
Read Solution (Total 9)
-
- Look upon the series carefully
2,20,10,100,50...
2 * 10 = 20
20/ 2 = 10
10 * 10 = 100
100/2 = 50
similarly
50 * 10 = 500 - 11 years agoHelpfull: Yes(5) No(0)
- 500
Multiply by 10 & divide by 2
[2*10=20],[20*1/2=10],[10*10=100],[100*1/2=50],[50*10=500],..
- 11 years agoHelpfull: Yes(2) No(0)
- two sequences... (multiply by 5)
2, 10, 50
20,100.... 500 - 11 years agoHelpfull: Yes(2) No(2)
- two sequence....
2,10,50..
20,100,...
multiplying each no in the sequence by 5
so.. next no will be 500(100*5) - 11 years agoHelpfull: Yes(0) No(0)
- 2*5=10*=50 like this 20*5=100*5=500.
- 11 years agoHelpfull: Yes(0) No(0)
- 500
series is 2*10=20
10*10=100 50
therefore 50*10=500 - 11 years agoHelpfull: Yes(0) No(0)
- thr 2 series
2*5=10 10*5=50
20*5=100
ans=100*5=500 - 11 years agoHelpfull: Yes(0) No(0)
- in this puzzle next series number is depend on resultant series
so first number is 2
second number is 2*10=20 (multiply with 10 in previous resultant number)
third number is 20/2=10 (half of previous resultant number)
fourth number is 10*10=100 (multiply with 10 in previous resultant number)
fifth number is 100/2=50 (half of previous resultant number)
sixth number is 50*10=500 (multiply with 10 in previous resultant number)
so the resultant next series number is 500 .........answer - 11 years agoHelpfull: Yes(0) No(0)
- 2*10=20
20/2=10
10*10=100
100/2=50
50*10=500
So next number is 500 - 10 years agoHelpfull: Yes(0) No(0)
