What is the sum of 4 2/4 + 7 4/5 ?
the space between fractions is because there are whole numbers 4 and 7

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

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
