Answer:

Example 11 answer = 12

Step-by-step explanation:

40, 36, 32, 28

is an arithmetic sequence.

The first term (a) is 40

The common difference (d) is -4

The formula for finding the nth term (X_{n} in an arithmetic sequence is;

X_{n} = a + d(n - 1)

X_{8} = 40 + -4(8 - 1)

X_{8} = 40 - 28 = 12
