Problem
Three positive numbers are in geometric progression. If the first term is and the third term is , what is the common ratio? a) b) c) d)Intuitive explanation
A geometric progression links terms by multiplying by the same constant each time—that's your common ratio . Since you know the first and third terms, you can set up an equation: the third term equals the first term times applied twice. This gives you a direct path to find without needing the middle term.
