Question
-3 -10 -40 -185 -905 -4500 -4 a b c d e
Find the value of d. 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, ( -3 + 1 ) × 5, ( -10 + 2 ) × 5, ( -40 + 3 ) × 5, ( - 185 + 4 ) × 5, ( - 905 + 5 ) × 5 Completing the next series as, -4, a = ( -4 + 1 ) × 5, b = ( -15 + 2 ) × 5, c = ( -65 + 3 ) × 5, d = ( -310 + 4 ) × 5 Value of d = - 1530
