This number sequence was in costa coffee today and if u win u get a free drink ..anyone have a clue what the missing number is ? I’ve looked at it for ages and cant work it out which is unusual, as I am normally competent at these basic logic questions
1, 2 , 6, 11, ?, 86, 946
23 July, 2017 at 10:21 pm #1062084First guess would be 77
23 July, 2017 at 10:22 pm #1062085add a prime number then times it
23 July, 2017 at 10:26 pm #1062086Needless to say, the only person likely to be able to answer is possibly drac so for once surprise me and lets have a display of intelligence on this site instead of random crap about the cat sitting on the mat in the poetry club or feeling guilty about not doing your dads garden living at home mid 30s. 86 multiplied by 11 is clearly 946 yet the 11 is 2 places to the left instead of just the 1.

23 July, 2017 at 10:29 pm #1062089It is a succession of adding then multiplying prime numbers
23 July, 2017 at 10:30 pm #1062090next you would add 13…then you would times that number by 15
