Answer:

2.56

Step-by-step explanation:

I went through the days, doing whatever operation it instructed to do. Monday, Multiply 2.21 by two. Tuesday, add .39 to 4.42, you're left with 4.81. Wednesday, subtract 1.76. You're left with 3.05. 4/5 of 3.05 is 2.44. Friday, add .12 to 2.44. His share is worth 2.56 at the end of the week. Hope this helps.

The first term of an arithmetic sequence is -5, and the tenth term is 13.
Nitella [24]

Answer:

The common difference is 2

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1+d(n-1)

a1 = -5

a10 = 13

Substituting n=10 a10=13 and a1 =-5

13 = -5 +d (10-1)

13 = -5 +9d

Add 5 to each side

13+5 = -5+5 +9d

18 = 9d

Divide each side by 9

18/9 = 9d/9

2 =d
