If 45.65

( 22, 19.5, 21.45), (33, 30.5, 33.55),( 44, 41.5 , x)

first terms of brackets => 22 , 33 , 44
second terms of brackets => 19.5 , 19.5 + 11 , (19.5 + 11*2)
third terms of brackets => 21.45 , (21.45 + 12.1) , (21.45 + 2*12.1)

=> x = 21.45 + 2 * 12.1 = 45.65

c)45.65
break d series into 3 as:
(22,33,44), (19.5,30.5,41.5) and (21.45,33.55,____)
1st series: 33-22=11, 44-33=11
2nd series: 30.5-19.5=11, 41.5-30.5=11
3rd series: 33.55-21.45=12.10, so next term will be 33.55+12.10=45.65

Subhajit Mitra  (7 years ago)

22,19.5,21.45,33,30.5,33.55,44,41.5
22-2.5= 19.5; 22- 0.55= 21.45;
33- 2.5= 30.5; 33+ 0.55= 33.55;
44- 2.5= 41.5; 44- 0.55= 43.45
so, 43.45 can be the answer.
This is going with the series as well. But how come it's not in the option?
Plzz enlighten me if I'm wrong..
