Step-by-step explanation:
Q. (3)
Ans.- Here , We will have to multiple
by 2 the all no. and add 1 , 2 ,3 ,
4 in it respectively .
As- 5 , 5×2 + 1 = 11
11×2 + 2 = 24
24×2 + 3 = 51
51×2 + 4 = 106
In the giving sequence -
5 , 11 , 24 , 52 , 106
Wrong term is 52 .
Q. (4)
Ans.- 7 , 9 , 7 + 9 = 16 , 16 + 9 = 25
25 + 16 = 41 , 41 + 25 = 66 ,
66 + 41 = 107
In the giving sequence -
7 , 9 , 16 , 25 , 41 , 66 , 105
Wrong term is 105 .
Q. (5)
Ans.- 8 , 8×3 = 24 , 24×3 = 72 ,
72 × 3 = 216
216×3 = 648
In the giving sequence -
8 , 24 , 72 , 248 , 648
Wrong term is 248 .
Q. (6)
Ans.- 10 , 10 + 80 = 90
90 + 80 = 170
170 + 80 = 250
250 + 80 = 330
330 + 80 = 410
In the giving sequence -
10 , 90 , 170 , 250 , 340 , 410
Wrong term is 340 .
