Question

Can someone PLEASE HELP ME with this, it’s DUE IN 1 HOUR pls help

Answer 1

A) 5n - 6

B) 44

C) 9

Explanation:

This is an arithmetic sequence

Tn = a + (n-1)d

a = -1

d = 9 - 4 = 5

Sn = -1 + (n-1)5

= -1 + 5n - 5

= 5n - 6

10th term

= 5(10) - 6

= 50 - 6

= 44

Tn = a + (n-1)d

39 = -1 + (n-1)5

39 = 5n - 6

5n = 39 + 6

5n = 45

n = 45/5

n = 9

Answer 2

so you basically keep adding by 5 in this formula

-1,4,9,14,19,24,29,34,39

Explanation:

Use the formula

an=a1+d(n−1) to identify the arithmetic sequence.an=5n−6

each number is a term the nth is 5
