Question

problem 2 using inductive reasoning got it? what conjecture can you make about the twenty - first term in r, w, b, r, w, b, …?

Explanation:

Step1: Identify sequence cycle

The sequence repeats every 3 terms: R, W, B.

Step2: Calculate term position in cycle

Divide 21 by the cycle length 3:
$\frac{21}{3} = 7$
This means the 21st term is the last term of the 7th full cycle.

Answer:

The twenty-first term is B.
