Number Sequences - Geometric, First Terms (Level 1)

This math topic focuses on identifying the first three terms of geometric number sequences. Each question presents a different exponential sequence, requiring the learner to calculate powers of bases such as 4, 3, 9, 5, and 8. Problems assess the ability to find first terms based on various starting indices like p, m, n, b, r, and x. Further complexity is added by offering multiple choice answers, prompting the learner to verify their calculations against given options. This exercise is ideal for building skills in pattern recognition within geometric progressions.
