the 7th term of geometric series is 1/128 and the 11th term is 1/2048 - if r < 0.
determine the first term of the sequence
will the sequence converge? explain
a new series is formed by taking T2 + T3 + t5 + ... - 1/2 + 1/8+1/32 + ...
from the above sequence
calculate the sum to infinity of this new series
