Answer:

12

Step-by-step explanation:

4 × 3 = 12

3/3 = 12

2/3 = 8

1/3 = 4

8 slices were eaten and 4 are left, and if you add 8 + 4 or you multiply the 3 × 4, you get 12. There were originally 12 slices.

Part one: Sequence and Series

ASHA 777 [7]

Answer:

- 57

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a + (n - 1)d

where a is the first term and d the common difference

Here a = 13 and d = - 2.5, thus

$a_{29}$ = 13 + (28 × - 2.5) = 13 - 70 = - 57
