Guys
I'm struggling to find a way to recognise a pattern on an array/list of numbers.
There are 80 ordered numbers as below, but I would like to find a pattern of this list. Initially I tried Second minus First, 3rd minus Second, etc. Where looked like a number that could be divided by 2. But this pattern is not accurate and varies.
So I would like to find a way to recognise a possible pattern. Below my numbers separeted by comma.

{36,44,56,64,68,74,106,112,142,192,265,294,295,313,337,373,379,390,406,441,454,470,508,522,561,563,719,728,734,751,756,759,779,820,824,842,873,910,942,950,963,986,1024,1030,1060,1079,1145,1150,1180,1222,1275,1410,1428,1434,1435,1443,1457,1478,1482,1511,1550,1559,1560,1581,1597,1607,1612,1643,1672,1680,1693,1702,1770,1823,1845,1866,1878,1916,1934,1968}

Excel Facts

What does custom number format of ;;; mean?
Three semi-colons will hide the value in the cell. Although most people use white font instead.
I don't really get what you're after.

If you chart the data, you can see there is a clear uptrend with occasional bumps.

I still don't get what you're after. Please explain. The line looks linear.

Excel has the ability to find curves/trendlines (e.g. LINEST Nonlinear Regression/polynomial Regression), and can give you a formula. But this formula is just an estimate (a curve/trendline).
If you want a PATTERN like in the example in your last post, I don't know if Excel is capable of that or not. I know that Wolfram Alpha is/was supposed to be able to do it, but I never had much luck in it being able to extract patterns for me.

Here are 2 example links of Excel curve fitting: Using LINEST for non-linear curve fitting, NONLINEAR CURVE FITTING IN EXCEL
