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 the place of the question mark '?' in the following number series?
234, 238, 252, 276, ?, 354
The pattern followed by the series is
234 + 4 = 238
238 + 14 = 252
252 + 24 = 276
276 + 34 = 310
310 + 44 = 354
What should come in place of the question mark '?' in the following number series?
287, ?, 71, 35, 17, 8
The series follows the following pattern:
8
8 × 2 + 1 = 17
17 × 2 + 1 = 35
35 × 2 + 1 = 71
71 × 2 + 1 = 143
143 × 2 + 1 = 287
∴ The missing term in the series is 143.
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
What should come in place of the question mark '?' in the following number series?
