(d) a b a b

(e) None of these

ANSWER & EXPLANATION

- (d):

The pattern is -4, -9, -16, …. i.e. -2, -3, -4, …. So, missing term = 169 -5 = 169 -25 = 144.

- (b):

The pattern is + (5*1), +(5*2 ), +(5*4), +(5*8), +(5*16)

- (b):

1st letter: A- (+1)→ B- (+1)→ C- (+1)→ D- (+1)→E

2nd letter: Z (-5)→U +(5-2)= +3→X -(3-2)= -1→ W (+1- 2)=-1→V

3rd letter: Y (-5)→ T +(5-2)= +3→W -(3-2)= -1→V (+1- 2)=-1→U

- (a) ;
