If g is the geometric mean of 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, then which one of the following is correct ?

If the n^th term of a GP -2,4,-8,,16,…… is 1024. Find n.

The 6th term from the end of the G.P. 8, 4, 2, 1,...1/1024 (A) 1/64 (B)32 (C)1/32 (D)none of these

Which term of the G.P. 2,1, 1/2 , /4 …………is 1/(1024) ?

(1+x-2x^(2))^(6)=1+a_(1)x+a_(2)x^(2)+a_(2)x^(3)+....., then the value of a_(2)+a_(4)+a_(6)+......+a_(12) will be (a) 32 (b) 31 (c) 64 (d) 1024

Sum of first 10 terms of the series, S= (7)/(2 ^(2)*5 ^(2)) + (13)/(5 ^(2)*8 ^(2)) + (19)/(8 ^(2) *11^(2))+ …… is : (a) (255)/(1024) (b) (88)/(1024) (c) (264)/(1024) (d) (85)/(1024)
