Find the indicated term of the arithmetic sequence with the first term a1 and the common difference d. a. find a7 when a1 = –8 and d = 4. b. find a16 when a1 = 10 and d = 7.

a. a7 = a1 + (7 - 1)d

= -8 + 6*4

= 16 answer

b a16 = 10 + 15*7

= 115 answer

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
