What will come in place of the question mark (?) in the following number series?
11, 16, 23, 32, 43, ?
+5,+7,+9,+11, +13 difference
325, 314, 288, 247, 191, ?
325 - 11 = 314 314 - 26 = 288 288 - 41 = 247 247 - 56 = 191 191 - 71 = 120 The difference is increasing by 15.
105, ? , 116 , 144, 209 , 335
105 + (13 + 1) = 107
107 + (23 + 1) = 116
116 + (33 + 1) = 144
144 + (43 + 1) = 209
209 + (53 + 1) = 335
5, 12, 24, ?, 52, 68
2+3 , 5+7 , 11+13 , 17+19 , 23+29 , 31+37 17+19=36.
16, 22, 42, 84, 156, ?
First difference than multiplication
What should come in place of question mark (?) in the following questions?
24² – 6³ + √625 + 56 = ?²
576 − 216 + 25 + 56 = ?2 360 + 25 + 56 = ?2 441 = ?2 21 × 21 = ?2 ⇒ ? = 21
√x + 18% of 250 – 15% of 960 = -25
√x + 45 – 144 = -25 x = 5476
48% of 650 – 1105 ÷ 13 – 45% of 240 = 7x
312 – 85 – 108 = 7x x = 17
What will come in place of the question mark (?) in the following questions?(You are not expected to calculate exact values)
36.06% of 449.95 + √3140 – 17.96 X 12.92= x
162 + 56 – 234 =-16
[(9 × 3) / (27 × 81)] × [(274 / 92)] = 3?
