What are the first and last terms of this geometric series

11Alexandr11 [23.1K]

ANSWER

E. 10 and 640

EXPLANATION

The given series is

$\sum_{i=1}^45 \times 2^{2i-1}$

To find the first term of the series we substitute i=1 to get,

$a_1 = 5 \times {2}^{2 \times 1 - 1}$

$a_1 = 5 \times {2}^{ 1} = 10$

For the last term of the series, we substitute i=4 to obtain,

$a_4 = 5 \times {2}^{2 \times 4 - 1}$

$a_4 = 5 \times {2}^{7}$

This implies that,

$a_4 = 5 \times 128 = 640$

Therefore the correct answer is E

The length of the longest loaf of bread measured 1,405ft 1 3/4in. It was cut into slices 1/2in. thick. How many slices were ther

Paha777 [63]

1 inch would equal 2 slices of bread.
So there would be 24 slices in one foot.
multiply 1405 by 24 and you get 33720
so then add 3 to that from the 1 3/4
you know have 33723 1/2 slices of bread. because 3/4-1/2 would be 1/4 which is 1/2 a slice of bread.
so the answer would be 33723 1/2 slices of bread:)
