A triangle has one of length 10 and another of length 6. What is the possible lengths (x) of the side. Options:
4
6
10
16

6 & 10

Step-by-step explanation:

x+6>10

x>4

x<10+6

x<16

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
