Question 4.
Find the next term in 3, 7, 16, 35, 74?
Solution :
In the number series 3, 7, 16, 35, 74, … the difference between the terms is continuously increasing. Therefore, there is a possibility of obtaining the next term by multiplying the terms of the series with a number.
Here, 3 × 2 + 1 = 7,7 × 2 + 2 = 16,16 × 2 + 3 = 35,35 × 2 + 4 = 74 are obtained.
Thus, the next term will be 74 × 2 + 5 = 153.
