Sequence Pattern Analysis

The question presents a sequence: AB, ABB, ABBB, ABBBB, ? We need to find the pattern to determine the next term.

Identifying the Pattern

Observe the structure of each term in the sequence:

  • Term 1: AB (The letter 'A' followed by one 'B')
  • Term 2: ABB (The letter 'A' followed by two 'B's)
  • Term 3: ABBB (The letter 'A' followed by three 'B's)
  • Term 4: ABBBB (The letter 'A' followed by four 'B's)

The pattern is consistent: each term starts with 'A', and the number of 'B's following 'A' increases by one for each subsequent term in the sequence.

Determining the Next Term

Following the established pattern:

  • Term 1 has 1 'B'.
  • Term 2 has 2 'B's.
  • Term 3 has 3 'B's.
  • Term 4 has 4 'B's.

Therefore, the next term (Term 5) should have 5 'B's following the letter 'A'.

Term 5 = A followed by 5 B's = ABBBBB.

The next term in the sequence is ABBBBB.
