It looks like you have a sequence where it's x, x^2, (x+3), (x+3)^2.

So following this logic, the next two are 8, 64.

26 & 52

the pattern is multiply by the number(ex. 2x2=4) thats the answer then for the next answer you add one(ex. 4+1=5)

I see your reasoning for the 26, but not the 52. Was that supposed to be 26x26, or am I not understanding correctly?

2 is the first prime no.

4 is its square

The prime no. after 4 is 5.

Square of 5 is 25.

Then 29 is the prime no. after 25.square of 29 is 841.

After 841, 853 is tha next prime no.

ANSWER:

29,29^2=841
