Question
The question below is based on the given series I. The
series I satisfy a certain pattern, follow the same pattern in series II and answer the questions given below. I: 180, 358, 712, 1416, 2816, 5600 II: 124 …… 1920. If 1920 is the nth term, find the value of (n+2).Solution
Series I pattern: 180 * 2 – 2 = 358 358 * 2 – 22 = 712 712 * 2 – 23 = 1416 1416 * 2 – 24 = 2816 2816 * 2 – 25 = 5600 Series II pattern: 124 is the first term 124 * 2 – 2 = 246 246 * 2 – 22 = 488 488 * 2 – 23 = 968 968 * 2 – 24 = 1920 (5th term)
