What is the counterexample for "If two numbers are odd, then theri sum is odd"

a counterexample is 5+7=12

Step-by-step explanation:

this is because 5 and 7 are both odd numbers. when you add these numbers, you get 12. 12 is an even number.

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
