Question
72, 97, 147, ?, 322,
447 Find the missing number in the following number series:Solution
72 + (25 × 1) = 97 97 + (25 × 2) = 147 147 + (25 × 3) = 222 222 + (25 × 4) = 322 322 + (25 × 5) = 447
What approximate value will come in place of the question mark (?) in the following question?
? + (18.95 × 3.06) = 77.07? + 144.99 – 110.01 = 15.01 × 7.98
386.99 + 397.99 + ? - 232.02 = 35.02 × 31.99

13.232 + 19.98% of 549.99 = ? × 8.99
185.92 ÷ 5.98 - (4.002)2 + 114.03 of 5.03 ÷ 18.99 of 6.04 = 5.01 of 2.99 + ? ÷ 12.02
1242.12 ÷ √530 + 1139.89 ÷ 14.91 = ? + 45.39
