I'm not quite sure but the first one I'm pretty sure....
+3,+5,+7,+9 so then +11,+13,+15,+17,+19
24+11=35 => 6th term
35+13=48 => 7th term
48+15=63 => 8th term
63+17=80 => 9th term
80+19=99 => 10th term
14,34,54,74,94
Each increases by 20...
94+20= 114
114+20= 134
134+20= 154
154+20= 174
174+20= 194
37,46,55,64,73
Each increasing by 9,
73+9= 82
82+9= 91
91+9= 100
100+9= 109
109+9= 118
10.…….……......................
You probably jsut need to use law of cosines in order to solve for angle A
or
