407

I too came to 407 with my first attempt, but then I am coming to 426, but it is not building off the previous number, so I am not correct, but there is a nice little formula I concocted to get that, but it did not provide the right answer for 331, so I am still off base here.

I get 407, but that reduces the index to 1. So I cant get any higher.

 

[LouieP]

what about 411 ?

 

[Jonmo1]

The question does not ask to go any higher, it only asks for the next number.

 

[SteveO59L]

Well spotted

 

[Scott Huish]

No, the next number has not been given yet. There are numbers higher in the sequence than just the missing one I asked for.

Ok I found that by utilizeing the average of 2 numbers (a&b) and then the decreasing amount of the average (average of a&b minus the average of b&c) I got the answer of 410 for the next answer.

 

[Scott Huish]

Nope.

 

[Scott Huish]

OK, the first number is 1.
The square root of 1 is 1.
How can you utilize this to get the 2nd number, and then the rest?
There are no fractions in the answers, so fractional amounts are being ignored somewhere.
