What is the next term of the arithmetic sequence?
2,-1,-4, -7, -10,

-13 is the answer.

here -3 is added every time

-13

Step-by-step explanation:

Concept:

Here, we need to know how arithmetic sequences work.

An arithmetic sequence is a sequence or progression of numbers where the difference between each number is the same (or constant).

In simple words, you add or subtract the same number to get the next term in the sequence.

Solve:

{2, -1, -4, -7, -10}

2 - (-1) = 3

-1 - (-4) = 3

-4 - (-7) = 3

-7 - (-10) = 3

As we can see from above, the constant between the sequence is subtraction 3 or -3.

Therefore, in order to get the next term, we subtract 3 from the last term given.

-10 - 3 = -13

Hope this helps!! :)

Please let me know if you have any questions

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
