Central limit theorem

[Mmra]

Suppose X₁, X₂, ..., X_n are sequences of iid random variables with mean
equal to zero and variance = σ². we define Y_n =
s_n/(σ∗√n) −s_2n/(σ∗√2n)
, S_n =X₁ + X₂ +...+ X_n Using the central limit theorem, obtain the limit of the
sequence Y_n when n → ∞.

Can anybody help me pls?
