P = 18,000
R=6%
T=7 years
A = P ( 1 + 1 divided by r) raised to n
Substitute the numbers an u will fin the answer
75 because 7+77=84 and 84-9=75
Answer:

Step-by-step explanation:
Do a t chart with the factors and then add the greatest common factor (GCF) with the fraction
Given that the First term of the Arithmetic sequence = -3
⇒ a = -3
We know that nth term of a Arithmetic sequence is : Tn = a + (n - 1)d
where a is the first term and d is the common difference
Given that 10th term is 15
⇒ T₁₀ = -3 + (10 - 1)d
⇒ -3 + (10 - 1)d = 15
⇒ 9d = 18
⇒ d = 2
⇒ Common difference of given Arithmetic Sequence is 2
