This could be the start of *lots* of sequences. One possible answer is:
a(n) = n² + 1
a(0) = 0 + 1 = 1
a(1) = 1 + 1 = 2
a(2) = 4 + 1 = 5
a(3) = 9 + 1 = 10
etc.
So the answer would be:
1, 2, 5, 10, 17, 26, 37, 50, 65, 82, 101, 122, 145, 170, 197, 226, 257, 290, 325, 362, 401, 442, 485, 530, 577, 626, 677, 730, 785, 842, 901, 962, 1025, 1090, 1157, 1226, 1297, 1370, 1445, 1522, 1601, 1682, 1765, 1850, 1937, 2026, 2117, 2210, 2305, 2402, 2501...
Another way to think of is to add the next odd number...
1 + 1 --> 2
2 + 3 --> 5
5 + 5 --> 10
10 + 7 --> 17
17 + 9 --> 26
etc.
But again there are multiple interpretations, especially when you are only given 3 terms.

My guess is
1,2,5,12,29,70 ...............
I am not sure but what I did was double the term than add the number previous to that.
1 , (1+1+0) = 2 , (2+2+1) = 5 , (5+5+2) = 12 , (12+12+5) = 29
There could be other possibilities

There are many possibilities...
One is... times the no. by 3 and minus one... making the next two numbers 14 and 41
Another is square the no. and add one...

The previous number squared plus 1

The first thing comes to my mind is that they might be from prime number, so
1,2,5,7,11,13,17,19,23,29...
