7,4,1,-2 write a recursive and explicit rule for the sequence

recursive:

a(1)=7          a(n)=a(n-1)-3

explicit:

a(n)=7-3(n-1)

Step-by-step explanation:

for recursive you use a(n)=a(n-1) and then whatever the sequence is. Since yours goes down by 3, it would be -3 at the end.

For explicit, you use a(n)= first number in sequence+the difference in the sequence(n-1)

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.
