What’s the 30th of the linear sequence

-5,-2,1,4,7

The 30th term of the given sequence is 82.

Step-by-step explanation:

The nth term is given by the formula nth term = a + (n - 1) d

where  

a = first term

d = common difference

To find the 30th term in the given sequence :

The first term, a = -5 and the common difference, d = 3.

30th term = -5 + (30-1) 3

⇒ -5 + (29) 3

⇒ -5 + 87

⇒ 82

Therefore, the 30th term in the given sequence is 82.

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.
