To answer this question first we need to find out the pattern. To do this we will subtract. Lets do it:-
24 - 12 = 12
12 - 6 = 6
6 - 3 = 3
So the pattern in this is adding by the same number, Lets do it:-
3,6,12,24,
24 + 24 = 48
3,6,12,24,48,
48 + 48 = 96
3,6,12,24,48,96
96 + 96 = 192
3,6,12,24,48,96,192
192 + 192 = 384
3,6,12,24,48,96,192, 384
384 + 384 = 768
3,6,12,24,48,96,192, 384, 768
768 + 768 = 1536
3,6,12,24,48,96,192, 384, 768, 1536
1536 + 1536 = 3072
3,6,12,24,48,96,192, 384, 768, 1536, 3072
3072 + 3072 = 6144
3,6,12,24,48,96,192, 384, 768, 1536, 6144
6144 + 6144 = 12288
3,6,12,24,48,96,192, 384, 768, 1536, 6144, 12288
12288 + 12288 = 24576
3,6,12,24,48,96,192, 384, 768, 1536, 6144, 12288, 24576
24576 + 24576 = 49152
3,6,12,24,48,96,192, 384, 768, 1536, 6144, 12288, 24576, 49152
49152 + 49152 = 98304
3,6,12,24,48,96,192, 384, 768, 1536, 6144, 12288, 24576, 49152, 98304
So, d 15 term in dis pattern is 98304.
Hope I helped ya!! xD
