NMMS MAT HINTS - DOOZY STUDY 

1. 8, 14, 26, 48, 98, 194, 386

                       Each term in the series is less than twice the preceding term by 2.

                       So, 48 is wrong and should be replaced by (26 * 2 - 2) i.e. 50.

2. 3, 10, 27, 4, 16, 64, 5, 25, 125

                       The correct sequence is 3, 3², 3³, 4, 4², 4³, 5, 5², 5³

                       So ,10 is wrong and should be replaced by 32 i.e. 9.

3. 529, 361, 289, 171, 121, 49

                    7² = 49

                   11² = 121

                 13² = 136

                 17² = 289

                 19² = 361

                 23² = 529

4. 336, 210, 120, 62, 24, 6, 0

                 
                       a1= 0*1*2 =0
                       a2 =1*2*3 = 6
                       a3= 2*3*4= 24
                       a4 = 3*4*5 = 60
                       ....
                       ....
                       an=(n-1)n(n+1) 

5. 3, 2,8, 9, 13, 22, 18, 32, 23, 42

                     The given sequence is a combination of two series :
                    
                     I.   3, 8, 13, 18, 23  and
                   
                     II   2, 9, 22, 32,42
                   
                     The pattern in I is + 5 and the pattern in II is + 10.

                   
                     So, in II, 9 is wrong and must be replaced by (2 + 10)  i.e. 12
