Find the sum of the first 7 terms in the following geometric series. Do not round.
1024+512+256+...

2032

Step-by-step explanation:

From the sequence, it is evident that the next term is half of the initial term.

1024/2=512

512/2=256

256/2=128

128/2=64

64/2=32

32/2=16

Therefore, the terms are

1024, 512, 256, 128, 64, 32, 16

The sum of these six terms are

1024+512+256+128+64+32+16=2032

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
