p0 + p1 x + p2 x2 + ...,
as that term for which pi xi is largest. (Obviously this depends on x.) They then ask:
[Part 1, Problem] 120. [Prove that] the subscript of the maximum term increases as x increases. (One might consider this situation as somewhat unusual: in the course of successive changes the position of maximum importance is held by more and more capable individuals.)Problem 119 is to prove that for an everywhere convergent power series which is not a polynomial, the subscript of the maximal term goes to ∞ with x. Pólya and Szegö offer no commentary.
