In a fibonacci sequence the fourth term is 30 and the fifth term is 49.
Write down the first term in the sequence

49-30= 19

30-19=11

19-11=8

The first term is 8.

45

step-by-step explanation:

30+15

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.
