295, 286, 268, 241, 205, ?
Considering the above series-
295, 286, 268, 241, 205, ?
The logic of the series can be explained as,
295 – 9 = 286
286 – 18 = 268
268 – 27 = 241
241 – 36 = 205
By observing the pattern, we can write
205 – 45 = 160
⇒ ? = 160
∴ The value of ? is 160.
What should come in place of the question mark '?' in the following number series?
12, 23, 45, 78, ?, 177
The series follows the following pattern:
12 + 11 = 23
23 + 22 = 45
45 + 33 = 78
78 + 44 = 122
122 + 55 = 177
What should come in place of the question mark '?' in the following number series?
5, 15, 50, ?, 1030, 6185Given series:
5, 15, 50, ?, 1030, 6185
Calculation:
The series is following the below pattern,
5 × 2 + 5 = 15
15 × 3 + 5 = 50
50 × 4 + 5 = 205
205 × 5 + 5 = 1030
1030 × 6 + 5 = 6185
∴ The missing term in the series is 205.What will come in the place of the question mark ‘?’ in the following question?
35, 48, 63, ?, 99, 120CALCULATIONS:
⇒ 52 + 10 = 35
⇒ 62 + 12 = 48
⇒ 72 + 14 = 63
⇒ 82 + 16 = 80
⇒ 92 + 18 = 99
⇒ 102 + 20 = 120
