Let them appreciate that when the series grows so fast
(11641 in 4 steps). It is most likely to be an exponential
series i.e. 11 x 4 -4, 41 x 4 - 1
Exponential Series are like the ones described below. (i.e.
product of previous term)
8. 11, 41, 161, 641 _____ ANS: 2561
9. 5, 15, 60, 300, ____ ANS: 1800
10. 3505, 700, 135,___ ANS: 26.8
