CEDH : HDEC :: ? : PNRV

A
VRNP

B
RNPV

C
NRVP

D
VNRP

So, 135 is wrong.
Question 4
1 / -0

10, 26, 74, 218, 654, 1946, 5834

A
26

B
74

C
218

D
654

E
1946

Solution

2nd term = (1st term) x 3 - 4 = 10 x 3 - 4 = 26.
3rd term = (2nd term) x 3 - 4 = 26 x 3 - 4 = 74.
4th term = (3th term) x 3 - 4 = 74 x 3 - 4 = 218.
5th term = (4th term) x 3 - 4 = 218 x 3 - 4 = 650.
$$\therefore$$ 5th term must be 650 instead of 654.
Question 5
1 / -0

15, 16, 34, 105, 424, 2124, 12756

A
16

B
34

C
105

D
424

E
2124

Solution

2nd term = (1st term) x 1 + 1 = 15 x 1 + 1 = 16.
3rd term = (2nd term) x 2 + 2 = 16 x 2 + 2 = 34.
4th term = (3th term) x 3 + 3 = 34 x 3 + 3 = 105.
5th term = (4th term) x 4 + 4 = 105 x 4 + 4 = 424
6th term = (5th term) x 5 + 5 = 424 x 5 + 5 = 2125
$$\therefore$$ 6th term should 2125 instead of 2124.
