Which numbers are missing from this sequence?

6, 8, 10, _, _, 26....

I asked this question in "Jokes and Riddles" but nobody guessed right. So I decided to repost in "Mathematics". First correct gets the points.

No one has got it right yet. It's a lot easier than you think. The first number is 14......

You say no one has got it right yet? Look at my proof on the Internet. It may not be your answer, but it IS a correct answer, so I feel very disappointed.that you do not accept it.

6, 8, 10, 14, 20, 26, 34, 46, 62 is the sequence
It is an integer sequence, in this case, d=1


Ah, I just found the reference on the Internet.

The 2 missing numbers are 10 and 24.
Why?
6,8,10 are the sides of a right triangle
since 6²+8²=10².
The same is true of 10,24 and 26
since 10²+24²=26².
10,24,26 is the double of the 5,12,13 right triangle.
Question: Why all these bad answer markdowns??
All these answers are possibilities including mine!!
If you want to continue the sequence as I
have it, the next 3 numbers are 26,168 and 170,
the double of the 13,84,85 right triangle.
You can build up an infinite sequence
of Pythagorean triples this way
with the hypotenuse of any triangle
being the smallest leg of the next one!

2 times 4=8
2 times 5=10
