Number + 4 * (middle 2 digit number) = Next number. As in:

1588+4*58=1820
1820+4*82=2148

and so on

So 2284+4*28=2396 would be the next number.

Have to admit, I may have never gotten this one if it weren’t for the suggestive title. Thanks Suineg for the brain expansion for the day.

The title suggests that we have to take the “inside” numbers out and do something with them.

If the two numbers “inside” a given 4-digit number is large (58 for 1588), then the difference between that 4-digit number and the next one (1588, 1820) is also large (relative to other pairings).

Ah, yes, very good Bobo. I was spending too much time trying to double the inside numbers, should have doubled them twice!

I put double my inside out to give a clue, but if you dig deeper into the meaning you get an exact clue, the double of the double, because the middle distance is the distance from one extreme to the middle, if you then take your inside out, you are taking the double of the distance of that extreme to the middle, that its double and the you double your inside out so souble of the double!, I know its a little crazy explanation, but the hint could have been taking also like something to do with the number inside the whole number, cool man!

This puzzle was part of an iq test I took a year ago, but the question was without a hint, I got a perfect score so I assumed my reasoning was good, but I had to spend like 20 minutes in this item when I took the test, it was the last at least, cool!!
