The pattern that the series is following can be shown easily in a diagram: The above diagram means a term is divided by either 3 or 4 to get the next term. For example, 1548 when divided by 3 we get, 516. The divisor is oscillating between 3 & 4 in a manner like first 3 then 4 then again 3 then 4 and so on. That means to get the unknown term we have to divide 43 by 4. Because the previous operation was division by 3. ∴ The unknown term is 43 ÷ 4 = 10.75Related questions
