Question
Find the value of c. -3Â Â Â Â Â -2Â Â Â
 -12    -9    -100       -375  31    a      b     c     d             e In each of the following questions, a number series is given. After the series a number is given followed by (a), (b), (c), (d) and (e). You have to  complete the series starting with the number given following the sequence of the given series.Solution
The pattern of the first line series is obtained as, -3 × 1  + 1³ = -2 -2 × 2  - 2³ = -12 -12 × 3  + 3³ = -9 -9 × 4 - 4³ = -100 -100 × 5 + 5³ = -375 Completing the next series as, 31, a = 31 × 1 + 1³ = 32 b = 32 × 2 - 2³ = 56 c = 56 × 3 + 3³ = 195 The value of c = 195
