    What's the next number in the sequence?

    2, 10, 202..
    start with 2
    next term = 2(2^2 + 1) = 10
    next term = 2 (10^2 + 1) = 202
    then 2 (202^2 + 1)= 81610

    if a(n) is the nth erm
    the (n+1)th term is
    a(n+1) = 2 (a(n)^2 +1)

    Hey, your absolutely right. the answer is 81610. You have given the right explanation too. Are you a maths student?
