Write a recursive formula for the sequence 7, 13, 19, 25, 31, ... Then find the next term.

Answers

Answer 1
Answer:

Answer:

see explanation

Step-by-step explanation:

there is a common difference between consecutive terms , that is

d = 13 - 7 = 19 - 13 = 25 - 19 = 31 - 25 = 6

this indicates the sequence is arithmetic

the recursive formula lets us find any term in the sequence by adding the common difference to the previous term , that is

a_(n) = a_(n-1) + 6 ; a₁ = 7

the next term in the sequence is

31 + 6 = 37

At a candy store a bag holds up to 1 pound of candy. Each jawbreaker (x) weighs 0.25 pounds and each gumball (y) weighs 0.1 pounds. Which inequality shows the solution for all combinations of the two candies that will fit in the 1-pound bag?

Answers

x - number of jawbreakers;
y - number of gumballs.
The weight of jawbreakers + gumballs must be less than or equal to 1 pound.
Inequality that shows the solution for all combinations of the two candies is:
0.25 x + 0.1 y ≤ 1
