Question
The question below are based on the given Series-I. The
series-I satisfies a certain pattern, follow the same pattern in Series-II and answer the questions given below. I) 11 42, 1285, 1450, 1637, 1846 II) 101 1 ….1715. If 1715 is the nth term, what value should come in the place of (n-1)th term?Solution
Series – I, 1142 + (122 – 12) = 1285 1285 + (132 – 22) = 1450 1450 + (142 – 32) = 1637 1637 + (152 – 42) = 1846 Series –II, 1011 + (122 – 12) = 1154 1154 + (132 – 22) = 1319 1319 + (142 – 32) = 1 506 (n - 1)th term 1506 + (152 – 42) = 1715 1715 is nth term
