Question

Find the value of term a^14 in the sequence. 6,5,4,3,2

Answer 1

a^14? Or do you mean a sub 14...the 14th term?

Answer 2

please help me

Answer 3

The sequence is: a + (n-1)d

where a = first term, n = nth term, d = difference.

So in 6,5,4,... the difference is 5-6 = -1
and the first term, a , is 6.

so the sequence is 6 + (n-1)(-1)
which is 6 - n + 1
= 7-n

So the sequence is represented by 7-n.

So if you want the 14th term, substitute 14 for n, you get 7-14 = -7.

The 14th term is -7.

Answer 4

I understand alittle bit

Answer 5

In an arithmetic sequence, you know how to find the common difference, d, take the second term - first term, or take third term - second term...and in this case you get -1.

You know the first term is 6.

So just substitute into the formula a+(n-1)d

Answer 6

oh okay im taking math on the computer it's harder without a teacher

Understood.
