Make a list of possible pairs of numbers that have an gcf of 7

Some of the possible pairs are,

(7, 14), (21, 28), (28, 35), (42, 49), (63, 70).

Step-by-step explanation:

If two numbers have GCF( greatest common factor ) 7,

Then there are no common factor of these numbers other than 7,

∵ Multiples of 7 are,

7, 14, 21, 28, 35, 42, 49, 63, 70, so on,,,

Thus, some pairs which have GCF 7 are,

(7, 14), (21, 28), (28, 35), (42, 49), (63, 70).

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
