What effect does subtraction have on terms in parentheses when you remove parentheses

nswer:

Terms in parentheses are handled first. If the parentheses are removed, it will change the answer.

Step-by-step explanation:

example:

(4-3)2 reduced would be 2     (because the 4-3 would be handled first.)

4-3x2 reduced would be -2     (because the multiplication would be handled first.)

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
