16, because all the other numbers are odd and 16 is even
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
<span>To calculate the change in CPI we need to do a % change formula. (New - Old) / (Old) = n. (121 - 110) / 110 = .10. This is equal to a 10% change in CPI.
To confirm the answer, do, (Old) * (1+n) = New CPI. 110*(1+.10) = 121. It equals so it is right!</span>
