Question

PLease help me dont answer if u dont know

Answer 1

Answer:

Step-by-step explanation:

General arithmetic sequence formula:

where  = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula:

We have  and d = -7

So the formula to find the nth term would be

Answer 2

Answer:

$a_n=-8+(n-1)-7$

Step-by-step explanation:

General arithmetic sequence formula: $a_n=a_1+(n-1)d$

where $a_1$ = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula: $a_n=a_1+(n-1)d$

We have $a_1=-8$ and d = -7

So the formula to find the nth term would be

$a_n=-8+(n-1)-7$
