7as in a ,b can be 2 or 5
7
can someone give a hint
last 5 digits should be 34685 or 34692hence a+b is 7
3468517_ ? This can't be a solution right as you can't find a digit next to 7 to satisfy the given conditions?
The answer is 7.. Just do a recursive loop
See here is the full solution first three digits are 346fourth can be 8 or 9 let it be 9then fifth is 2, so the number is 34692sixth has to be 3 then the solution repeatslet the fourth digit be 8then fifth is 5 sixth is 1 seventh is 7 but no digit after that..Hence the recursive sequence of 5 digit appears..but the last 5 can be 34685 or 34692.. Hence the sum is 2+5= 7
7

ReplyDeleteSee here is the full solution
ReplyDeletefirst three digits are 346
fourth can be 8 or 9
let it be 9
then fifth is 2, so the number is 34692
sixth has to be 3 then the solution repeats
let the fourth digit be 8
then fifth is 5 sixth is 1 seventh is 7 but no digit after that..
Hence the recursive sequence of 5 digit appears..
but the last 5 can be 34685 or 34692.. Hence the sum is 2+5= 7
