Given that y-2=6, find y+4

Given:

To find:

Solution:

⇛y - 2 = 6

⇛y = 6 +2

⇛y = 8

substitute 8 in place of y

⇛y + 4

⇛8 + 4

⇛12

12 is the answer

.

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
