(1 sen y)2/(1-sen 2 y) -(1-sen y)/(1+sen y)= (1+2 sen y +sen2 y)/(cos2 y)-((1 sen y1-sen y)

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

yes because they have the same amount of green and blur marbles.
