Let me explain ..
445-3=442
442/2=221
221-3=218
218/2=109
109-3=106
106/2=53
53-3=50
50/2=25
25-3=22
22/2=11
11-3=8
8/2=4
So after 109 it should be 53.. in the given series it is 46 so
Have a nice day..!
445-3=442
442/2=221
221-3=218
218/2=109
109-3=106
106/2=53
53-3=50
50/2=25
25-3=22
22/2=11
11-3=8
8/2=4
So after 109 it should be 53.. in the given series it is 46 so
Have a nice day..!

4*2+3=11
11*2+3=25
25*2+3=53 ------------ 46 which is an wrong series.
53*2+3=109
109*2+3=221
221*2+3=445
You might can understand this.
11*2+3=25
25*2+3=53 ------------ 46 which is an wrong series.
53*2+3=109
109*2+3=221
221*2+3=445
You might can understand this.

I had solved this problem like this.
Starting from the end.
4.
4+7=11,
11+14=25,
25+21=46,
46+28=74. So 109 is wrong.
Can anybody say whether the way is correct are not? and why?

Yes 109 is wrong because 74* 35=2590 which is not the next number in the given series?
