Hi, in the given problem a geometric sequence is given a geometric sequence is given which is 4, 8, 16.
00:14
So, here the common ratio common ratio is 8 over 4 and that is equal to 16 over 8 which is equal to 2.
00:25
So, let us say the common ratio is given as r.
00:29
So, this implies r is equal to 2.
00:32
So, that is why it is a geometric sequence.
00:37
Now, the first term the first term of the given geometric sequence is geometric sequence is a is equal to 4 and the common ratio comes out to be r is equal to 2.
01:04
So, therefore, we know that nth term is a r to the power n minus 1.
01:10
So, this is formula for nth term calculation or finding of the nth term of the series...
