Write an explicit formula for a_na n
​
, the n^{\text{th}}n
th
term of the sequence 37, 34, 31,

40 - 3n

Step-by-step explanation:

This is an arithmetic sequence.

First term = = 37

Common difference(d) = second term - first term = 34 - 37 = (-3)

nth term = a + (n- 1)*d

               = 37 + (n -1)*(-3)

              = 37 + n*(-3) -1 *(-3)

             = 37 - 3n + 3

            = 37 + 3 - 3n

           = 40 - 3n

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
