157. (b) 4th term 23 = 5 × 4 + 3 = 23 D F H
3rd term 122 = 5 × 23 + 7 = 122 167. (b) The given logic is as floows.
2nd term ? = 5 × 122 + 11 = 621

1st term 3120 = 5 × 621 + 15 =3120
158. (b)
159. (c) The pattern is-

acdb dacb cdab acdb da
\ GHI is the next group.
160. (c) 168. (d)
9 × 2 + 1 = 18 + 1 = 19 169. (a) c c b a b b c a a a b c c c b a b
19 × 2 + 2 = 38 + 2 = 40 170. (a)
40 × 2 + 3 = 80 + 3 = 83 171. (c) 4 6 10 16 24 34
83 × 2 + 4 = 166 + 4 = 170
+2 +4 +6 +8 +10
170 × 2 + 5 = 340 + 5 = 345. Hence 340 is wrong.
161. (d) 21 + 7 = 28 +2 +2 +2 +2
28 + 5 = 33 172. (c) 3 5 9 17 33
33 + 3 = 36
+2 +4 +8 +16
36 + 1 = 37
37 – 1 = 36 2×2 4×2 8×2
Hence, 35 is wrong. 173. (d) FAK . IEM LIO OMQ
162. (a) 5 + 8 = 13, 13 + 16 = 29, 29 + 32 = 61 The given series is
61 + 64 = 125 125 + 128 = 253 F A K
\ 120 is wrong. +3 +4 +2
163. (b) 0 + 7 = 7, 7 + 21 = 28, 28 + 35 = 63 I E M
63 + 61 = 124, 124 + 87 = 211 +3 +4 +2
\ 215 is wrong. L I O

174. (a) 3, 5, 35, 10, 12, 35, 17, 19
+1 +2 +4 +8 +16 The given logic is

165. (b) The given logic is as follows,
+7 +7 0

where, 5 × 2 = 10 17 19
10 × 2 = 20 175. (b) 36, 34, 30, 28, 24, 22
20 × 2 = 40 –2 –4 –2 –4 –2
40 × 2 = 80
