  • Question 2
    1 / -0
    In the following question, the wrong term and its substitution by the correct term are indicated as a pair in the four options given below. Identify the correct pair.
    24,49,99,94,15,31,59,5824, 49, 99, 94, 15, 31, 59, 58
    Solution
    Consider the first four terms and the second four terms.
    15,31,59,5815, 31, 59, 58 are related as below
    31=2×15+131=2\times 15+1
    59=4×15159=4\times 15-1
    58=4×15258=4\times 15-2
    Consider 24,49,99,9424, 49, 99, 94
    49=2×24+149=2\times 24+1
    99=4×24+399=4\times 24+3
    94=4×24294=4\times 24-2
    Change 9999 to 9595 and we have
    95=4×24195=4\times 24-1

    The correct pair is (99,95).(99,95).

    The given series is 2,12,32,63,102.2,12,32,63,102.
    Here, if 6363 is changed to 6262, differences between consecutive terms become 10,20,30,4010, 20, 30, 40 which is a pattern of uniform increase.
