Q.7 Write variable expressions for arithmetic sequences
Write an expression to describe the sequence below. Use n to represent the position of a term in
the sequence, where n = 1 for the first term.
-8, -16, -24, -32, ...

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
