The logic of the series can be explained as,

2 × 3 + 1 = 7

3 × 4 + 1 = 13

4 × 5 + 1 = 21

5 × 6 + 1 = 31

6 × 7 + 1 = 43

By observing the pattern, we can write

7 × 8 + 1 = 57

⇒ ? = 57

∴ The value of ? is 57.

Explanation:

The series follows following pattern:

⇒ 144 + 20 = 164

⇒ 164 + 30 = 194

⇒ 194 + 40 = 234

⇒ 234 + 50 = 284

By observing the pattern, we can write

284 + 60 = 344

⇒ ? = 344

Explanation:

Considering the above series,

3, 9, 27, 57, 99, ?

The logic of the series can be explained as,

9 – 3 = 6 = (6 × 1)

27 – 9 = 18 = (6 × 3)

57 – 27 = 30 = (6 × 5)

99 – 57 = 42 = (6 × 7)

By observing the pattern, we can write

? – 99 = 54 = (6 × 9)

⇒ ? = 153

∴ The value of ? is 153.

5. 180, 174, 162, 144, 120, ?

The logic of the series can be explained as,

180 – (6 × 1) = 174

174 – (6 × 2) = 162

162 – (6 × 3) = 144

144 – (6 × 4) = 120

By observing the pattern, we can write

Show Correct Answers

Correct Answers: C. 1120

Explanation: The pattern of the number series is:

150 × 2 – 1 × 10 = 290

290 × 2 -2 × 10 = 560

560 × 2 – 3 × 10 = 1090 ≠ 1120

1090 × 2 – 4 × 10 = 2140

2140 × 2 – 5 × 10 = 4230

Hence 1120 is wrong Number.

129 + 42 = 145

145 + 32 = 154

Hence 102 is wrong Number.

527 + 92 = 608

608 + 72 = 657

282 + 19 = 803

292 + 23 = 864

302 + 29 = 929 ≠ 930
