i hope the answer for the series 7,4,6,3,4,5,1,5,2,25 might be as follows
break the series into two series
take the 1st series(alternative numbers) 7,6,4,1,2,4,x
7-6=1
6-4=2
1-2=1
4-2=2
so ans might be 4

I think 3rd one is-
1.25, 3, 7.1, 1.50, 1, 8.1, 1.75, -1, 9.1, 2.0
break into 3 parts
1.25, 1.50, 1.75, 2.00
3, 1, -1..... (-3)
7.1, 8.1, 9.1... (10.1)
so ans is -3

7,6,4= 7:7-1:7-3=7:6:4....... 4,3= 4,4-1 ............. 5 , 1, 5^1 , 5 5^2 25 so next number in d series is 5 it goes on 5 5^3 5 5^4................

5,9,7,2,25,51,16,8,6,
firstly divide the series as (5,9), (7,2), (25,51),(16,8),(6,-)
take alternate series as(5,9), (25,51),(6,-)
2*5-1=9
2*25+1=50+1=51
2*6-1=12-1=11

507/3=169;
248/4=62;
36/3=12;
168/4=42;
168/3=59;
divide alternate numbers with 3,4
