Answer 1

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
