Find the explicit formula for the sequence -29, -37, -45, -53, A) an= -7n - 29
B) an = -7n - 22
C) an = 7n - 43
D) an = -8n - 21

D) an = -8n - 21

Step-by-step explanation:

Let's plug 1 into each to see what we get.

A) -7-29 = -36  We can rule this out

B) -7-22=-29

C) 7-43=-36  We can rule this out

D) -8-21=-29

So, we have B and D that could still work.

Let's plug in 2 now.

B) -14-22=-36  We can rule this out

D) -16-21=-37

Plugging in 3 and 4 gives us -45, and -53.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
