How to find missing terms in a arithmetic sequence if there is no middle term?
kozerog [31]
You would use the formula for the specific term you wish to find;
The formula is:
U_{n} = a + (n - 1)d
a = starting value of the sequence
d = the common difference (i.e. the difference between any two consecutive terms of the sequence)
n = the value corresponding to the position of the desired term in the sequence (i.e. 1 is the first term, 2 is the second, etc.)
Un = the actual vaue of the the term

For example, if we have the arithmetic sequence:
2, 6, 10, 14, ...
And let's say we want to find the 62nd term;
Then:
a = 2
d = 4
(i.e. 6 - 2 = 4, 10 - 6 = 4, 14 - 10 = 4;
You should always get the same number no matter which two terms you find the difference between so long as they are both consecutive [next to each other], otherwise you are not dealing with an arithmetic sequence)
n = 62

And so:
U_{62} = (2) + (62 - 1)(4) \\
= 2 + 61(4) \\
= 2 + 244 \\
= 246

Answer:

A=p(1+r/12)^6

Here  r = 0.09, P = $1000 so

Amount of money needed to pay off the loan =

1000(1 + 0.09/12)^6

= $1045.85.
