Question
A series is given with two terms missing. Choose the
correct alternatives from the given ones that will complete the series. 85, 92, 78, 99, ___, 106, 64, ___Solution
The logic followed here is as follows: Alternatively, the numbers are added and subtracted by the consecutive multiples of 7 starting from 7. 85 + 7 = 92
92 – 14 = 78
78 + 21 = 99
99 – 28 = 71
71 + 35 = 106
106 – 42 = 64
64 + 49 = 113
So, ‘71, 113’ will complete the series.
