A sequence is defined as follows: Start with any positive integer value (๐). Each term is found from the previous term as follows: If the value is even, divide it by 2 (๐/2). If the value is odd, multiply it by 3 and add 1 (3๐+1).
Q2.
If the first term of the sequence is 30, what would the second term be?
100
Correct answer: 15
