AI explanation

The series is constructed by taking consecutive integer steps and repeating each integer exactly twice before moving to the next. The sequence progresses as two 2s, two 3s, two 4s, and two 5s, before continuing to two 6s, two 7s, and two 8s. Following this established repetition pattern, the missing term after the number 4 is 5.
