Use the fomula a_(n)= a_(1)+ d(n-1)
Answer:
14 miles
Step-by-step explanation:
Isaac is walking 14 miles because if it is seven miles to the store, he has to walk seven miles back. Seven plus seven is fourteen.
Why is this answer incorrect?
There are decimal places that are closer to 500.
What is the correct answer?
I believe it would be 499.9 with a bar over the last 9
Hope this helps!
Answer:
3
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a +(n - 1)d
where a is the first term and d the common difference
Given the fifteenth term is - 67, and term 21 is - 97, then
a + 14d = - 67 → (1)
a + 20d = - 97 → (2)
Subtract (1) from (2) term by term
6d = - 30 ( divide both sides by 6 )
d = - 5
Substitute d = - 5 into (1)
a + 14(- 5) = - 67
a - 70 = - 67 ( add 70 to both sides )
a = 3
Thus the first term is 3
You just combine 16 and g to get 16g.
