Correct Answer: 9
Solution : Given: 4, ?, 19, 39, 79, 159
The pattern followed here is – 4 + (5 × 1) = 4 + 5 = 9 9 + (5 × 2) = 9 + 10 = 19 19 + (5 × 4) = 19 + 20 = 39 39 + (5 × 8) = 39 + 40 = 79 79 + (5 × 16) = 79 + 80 = 159
So, 9 is the missing term of the series. Hence, the fourth option is correct.
