In a sequence, the first term is 2 and each subsequent term is obtained by adding the previous term to its square. What is the fifth term?
To find the fifth term in the sequence, we need to follow the rule that each term is obtained by adding the previous term to its square:

Term 1 = 2

Term 2 = Term 1 + (Term 1)^2
           = 2 + (2^2)
           = 2 + 4
           = 6

Term 3 = Term 2 + (Term 2)^2
           = 6 + (6^2)
           = 6 + 36
           = 42

Term 4 = Term 3 + (Term 3)^2
           = 42 + (42^2)
           = 42 + 1764
           = 1806

Term 5 = Term 4 + (Term 4)^2
           = 1806 + (1806^2)
           = 1806 + 3,258,036
           = 3,259,842

So, the fifth term in the sequence is 3,259,842.
