Directions: What should come in place of the question mark (?) in the following number series.
5, 8, 21, 75, ?The pattern of the given series:
⇒ 5 × 1.5 + 0.5 = 8
⇒ 8 × 2.5 + 1 = 21
⇒ 21 × 3.5 + 1.5 = 75
⇒ 75 × 4.5 + 2 = 339.5 =?
∴ The missing number of the series = 339.52. What will come in place of the question mark (?) in the following equation? 2 × 98 = ? × 100 – 2 × 2
3. What will come in place of question mark (?) in the following number series? 11 12 26 81 ?
8. What will come in place of question mark (?) in the following question? 185 + 376 - 120 = 979 - ?
