Recall that $2^{10} = 1,024$. For $15$ cycles: $2^{15} = 32768$. Multiply by initial $20 \implies 655,360$.
Using the PCR exponential amplification equation $N = N_0 \times 2^n$: Substitute $N_0 = 20$ and $n = 15$: $$N = 20 \times 2^{15} = 20 \times 32768 = 655,360.$$ Each thermal cycle doubles the template quantity....
