    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?

    A 1498 Correct Answer Incorrect Answer
    B 1464 Correct Answer Incorrect Answer
    C 1506 Correct Answer Incorrect Answer
    D 1562 Correct Answer Incorrect Answer
    E 1587 Correct Answer Incorrect Answer

    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
