Which of these sequences are linear? A.) 6, 11, 16, 21
B.) 1, 3, 9, 27
C.) 7, 4, 1, -2
D.) 0.5, 0, -0.5, -1

Pls answer :)

Hii! it’s A as between each number there is 5. for a sequence to be linear the numbers all need to have the same exact number between them. idk if it makes sense lol.

221,500 is the answer

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
