REAL TOUGH ONE

ReplyDeleteIt's the number coming in between twin primes...... For example 6 is coming between 5 and 7

Delete114, 126, 138

Deleteisn't it just like 126

Delete138, 150, 180, 192, 198, 228, 240, 270, 282....

ReplyDelete138,150,180....

ReplyDelete114.

ReplyDelete132,138,150.....

ReplyDeleteif x is the number in the series, then x-1 and x+1 are the prime numbers

133 is not prime ..19x7 = 133 .. :P

Delete4, 6, 12, 18, 30, 42, 60, 72, 102, 108 which

ReplyDeleteare the middle numbers of twin primes (3, 5), (5, 7), (11, 13), (17, 19), (29, 31), (41, 43)....

So the answers are 138(137,139), 150(149,151), 180(179,181)...

seems to be correct

Deletecorrect answer

Deleteperfect buddy

DeleteStill wrong due to the wording of the riddle. It asks for the next 3 numbers, not the next 3 sets of numbers. Any answer beyond 138 demonstrates a comprehension error.

Delete120,122,126

ReplyDeletelite thesuko !!

ReplyDelete007

ReplyDeletegreat ans

ReplyDeletepls give me next nuber....35,28,29,94,83.............

ReplyDeletewhat is souliotion

n

ReplyDelete133

ReplyDelete130,148,160

ReplyDelete114.124.136

ReplyDeleteAddition of the numbers loops and it gets reduced one addition everytime the loop restarts. So this time it is 6+6+12+12... instead of 2+6+6+12+12

Sorry for bad english.

such a waste question

ReplyDeletethokku time waste

ReplyDelete114,120,126 this is right answer friends

ReplyDeleteits a real tough one,not so easy to solve

ReplyDelete112

ReplyDeleteIt is a simple calculation add them all together find the value of off all the numbers then subtract it from the next number and divide by nearest prime number then half it and half it again then square it an that's your answer. Easy her.

ReplyDeletereally a good question to solve...

ReplyDelete114,120,126

ReplyDeleteList the prime numbers in sequence starting from 5. Subtract one from each prime and that yields this number sequence. You can find the missing three numbers easily now...

ReplyDelete160, 166, 226

ReplyDeleteThe answer is 138, 150, and 180

ReplyDelete4,6,12,18,30,42,60,72,102,108,138,150,180

when you subtract 1 from each number you get all prime numbers

3,5,11,17,29,41,59,71,101,107,137,149,179

and when you add 1 to each number you get all prime numbers

5,7,13,19,31,43,61,73,103,109,139,151,181,

Analyzing further, the sequence is...

ReplyDelete4, 6, 12, 18, 30, 42, 60, 72, 102, 108, 138, 150, 180, 192, 198, 228, 240, 270, 282, 312, 348, 420, 432,

and the distance between the numbers are....

2, 6, 6, 12, 12, 18, 12, 30, ((6, 30, 12, 30, 12,)) (( 6, 30, 12, 30, 12,)) 30, 36, 72, 12,

I've found some patterns, but can't seem to find a pattern in the 2,6,6, 12 sequence. Can anyone else help me?

u r right frnd....i too find some patterns...that is 2,6,6,12,12,18,12,30,

Deletethe alternate series..2,6,12,12,6,2

and also 6,12(6*2),18(6*3),30(6*5).... the next may be 6*7 if taken as a odd series... or 6*8( if 2+1,3+2,5+3

so the answer is 150,152,206,or 156,158,230

this is also the right one..... there is no exact answer for this Question...

easy 114, 120, 126

ReplyDeleteok I get the distance I tried that I got the prime numbers but I still don't understand why is it the number from 108 gone to 138

ReplyDelete4,6,12,18,30,42,60,72,102,108

ReplyDeleteDiving by 6 from the second one ...

1,2,3,5,7,10,12,17,18

Now the relation...

12 = 6 * (2/1)

18=6*(3/2)

30=18*(5/3) ...

x th number = (x-1) th number * ((xth number/6)/((x-1) th number/6))

but i am not sure how could i include 4 in this series ... with this logic the next number will be 114...

114, 126, 138

ReplyDelete: ( I don't really get it... Some of your theories make sense...

ReplyDelete114, 126, 138

ReplyDelete114,120,126

ReplyDelete138,192,198.The logic is, the number inbetween twin primes

ReplyDeletethe number that's in between the consecutive prime numbers so the answer is 138 150 180 192 198 228 and goes on
