Directions (6-10): In each of the following questions a number series is given. A number in the series is suppressed by letter ‘A’. You have to findout the number in the place of ‘A’ and use this number
to find out the value in the place of the question mark in the equation following the series.

6) 42 62 92 132 A 242 312
A + 14 = ? × 14

7) 4 7 12 19 28 A 52
A² - 4 = ?

8) 18 24 A 51 72 98 129
A*3/7*4/5= ?

9) 36 216 64.8 388.8 A 699.84 209.952
A ÷ 36 = ?

10) 188 186 A 174 158 126
under root (A-3) = ?
