Ex.1. Which number would replace question mark in the series 2, 7, 14, 23, ?, 47

 (a) 28 b) 34 (c) 31 (d) 38

Sol. The given sequence is +5, +7, +9,.......... i.e. 2+5=7; 7+7= 14; 14+9=23 So, missing number=23+11=34 Hence, the answer is (b) 


Ex.2. Complete the series : 4, -8, 16, -32, 64 (....) 

(a) 128 (b) -128 (c) 192 (d) -192
