problem

For a nonempty set

S

of integers, let

\sigma(S)

be the sum of the elements of

S

. Suppose that

A = \{a_1, a_2, \ldots, a_{11}\}

is a set of positive integers with

a_1 < a_2 < \cdots < a_{11}

and that, for each positive integer

n \le 1500

, there is a subset

S

A

for which

\sigma(S) = n

. What is the smallest possible value of

a_{10}

Plain-text mathematical notation (without MathML)

For a nonempty set S of integers, let σ(S) be the sum of the elements of S . Suppose that A={a₁,a₂,…,a₁₁} is a set of positive integers with a₁<a₂<⋯<a₁₁ and that, for each positive integer n≤1500 , there is a subset S of A for which σ(S)=n . What is the smallest possible value of a₁₀ ?

Original LaTeX notation

For a nonempty set $S$ of integers, let $\sigma(S)$ be the sum of the elements of $S$ . Suppose that $A = \{a_1, a_2, \ldots, a_{11}\}$ is a set of positive integers with $a_1 < a_2 < \cdots < a_{11}$ and that, for each positive integer $n \le 1500$ , there is a subset $S$ of $A$ for which $\sigma(S) = n$ . What is the smallest possible value of $a_{10}$ ?
