What is the explicit formula for the sequence {3,8,13,18,…}?

the explicit formula is

Tn = 3 + 5(n - 1)

Step-by-step explanation:

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + d(n - 1)

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 3

d = 8 - 3 = 13 - 8 = 18 - 13 = 5

The explicit formula for the arithmetic sequence is

Tn = 3 + 5(n - 1)

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
