It's Trivial?-2

Algebra Level 5

Let \(a_n\)be defined as a sequence such that \(a_n\) is the geometric mean of the 6 numbers before it. Also,\(a_i=i^{21},1 \leq i \leq 6\).Let \(a_\infty = L\). Find number of trailing zeros of \(L\).

Note:-trailing zeros means number of zeros at the the end of the number. Ex:-120 has 1 trailing zero
