The first term of an arithmetic sequence is -30 and the common difference is 8. Find the 20th term.

122.

Step-by-step explanation:

nthe term = a1 + d(n - 1) so here:

20th term = -30 + 8(20 - 1)

- 30 +  152

= 122.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
