6
Step-by-step explanation:
46, 48, 64, 68, 86, 84
P= (2)(x-2)+(2)(5)
P= (x-2)+(x-2)+5+5
we know that
arithematic sequence will always have common difference
(a)
−5, −7, −10, −14, −19, …
we can see that


they are not equal
so, this is not arithematic sequence
(2)
1.5, −1.5, 1.5, −1.5, …
we can see that


they are not equal
so, this is not arithematic sequence
(3)
4.1, 5.1, 6.2, 7.2, …
we can see that


they are not equal
so, this is not arithematic sequence
(4)
−1.5, −1, −0.5, 0, …
we can see that


they are equal
so, this is arithematic sequence
If the point is dilated from the origin by a scale factor of 6
Then the coordinates of point A becomes
A( 6x7 , 6x9)
