BraidedLandscape6, May be you have overlooked it.
if you want prime no(s). you have missed 2 as a prime number.
But, adding odd prime no(s)./ prime numbers starting from 3 is fine. you may get 27 as answer which is also correct.

RapidCombat95281, just a boring reply:
a
(a+1)^2 - a^2 = 2a + 1,
Now, replace a by 0, 1, 2, 3 and so on, you get 1,3,5,7,9 ( the numbers you used to get you to the answer).

Milo, yes, true.

RapidCombat95281, it's the same thing. There's a proof for this. Take it from a mathematician.

RapidCombat95281, me too! Isn't math fascinating... I figured with such integrity in integrals & trueness in conclusions... there has to be a "higher power"... the entire universe is "held fast" by mathematical equations..., music, molecules, particals, medicine, etc. our bodies... just fascinating! Thank you Lord... and if we all evolved, all should have equal abilities & I'm no Einstein by any means...I'm artistic

BumBum, That is what they are... square numbers in a sequence.
Milo
RapidCombat95281, you can continue with squares and odd numbers, it goes the same way
