Excuse me ... NO ANSWER ??
I feel somehow that we have been ripped off.
So let US say that the answer is 42 and move our lives on as best we can.

Oh GOOD ...
Ahhh ... so it was a pattern of adding, subtracting or multiplying by the prime number sequence ... how devilish.
The pattern was:
Odd turn: (Even number: +, Odd number x)
Even turn: Even number: -, Odd number +)
Since the next prime number in the sequence was 37, and the next operation was multiply, then the answer was 1125 x 37 = 41625.
(The inherent problem with sequence questions, though, is that there can be multiple "right" answers.)

so true. their answer depends on the ways you solve, how you look at the problem, etc. this one was a little ... over the edge. who would have thought of a sequence consisting add, subtract, multiply, and division of prime numbers?

Way ahead of you. I've joined, have done this week's standard and bonus puzzles and am doing the reruns every day.
Current points: 86.
I'm still confused about how they can publish answers but then give the puzzles in the reruns though.

It wanted to be normal.

And I'm the one in seventeenth place, name: sam.
Of course that's a fake name as everyone knows my real name is mathsyperson.
