Please help! what is the explicit formula for this sequence?

D an = -7+3(n-1)

Step-by-step explanation:

-7,-4,-1,2,5,

To find the common difference, take the second term and subtract the first

-4 - -7

-4+7 = 3

We are adding 3 each time

The explicit formula

an = a1+d(n-1) where a1 is the first term and d is the common difference

an = -7+3(n-1)

a=r

d=q

c=p

b=s

hope this !

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
