Question 34

Select the number that can replace the question mark (?) in the following series.
88, 95, 106, 119, 136, 155, 178, ?

Solution

88 + 7 = 95

95 + 11 = 106

106 + 13 = 119

119 + 17 = 136

136 + 19 = 155

155 + 23 = 178

The next number in the series is obtained by adding consecutive prime numbers to the previous number

Similarly the next number is

178 + 29 = 207

Hence, the correct answer is Option C
