Given the following definitions: U = {1, 2, 3, 4, 5, 6, 7}
A = {1, 2,4,5)
B = {1, 3, 5, 7}
How many elements are in A'n B?

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

your answer is a

step-by-step explanation:

4*4*4*4=256

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

what is the question?
