    This is the only solution that worked for me in 2025. Defeats the purpose of reduce enum tho.

    Fixnum = Integer
Bignum = Integer

def sum_terms(n)
  (1..n).map{|m| m**2+1}.sum()
end

    Bignum=Integer Fixnum=Integer

    def sum_terms(n) (1..n).reduce(0) {|sum,n| sum + n**2 +1} end

    #NEVER DO THIS
class Object
	Bignum=Integer
	Fixnum=Integer
end

def sum_terms(n)
	1.upto(n).inject(0) {|sum, n| sum + n**2 + 1}
end

    what a terrible challenge. This is the most complicated way of doing n**2 + 1 given that the input is n=25
