Given the following sequence of keys [79,68,106,39,118,99], please answer the following questions if the hash function h(x) = (x mod 7) is used. Assume each bucket has only one slot and the bucket numbers start from 0.

Hash table with rehashing where the ith (i1) hash function is defined as: h_i(x)= (x+3*i²) mod 7.

What is the number in bucket 3?
