Use the initial term and the recursive formula to find an explicit formula for the sequence an. Write your answer in simplest fo
Ipatiy [6.2K]

Answer:

a_n = -11-14n

Step-by-step explanation:

Given

a_1 = -25

a_n = a_{n-1}-14

Required

The explicit formula

First, calculate a_2

Set n=2; So:

a_2 = a_{2-1}-14

a_2 = a_{1}-14

Substitute -25 for a_1

a_2 = -25-14

a_2 = -39

Calculate the common difference (d)

d = a_2 - a_1

d = -39 --25

d = -14

So, the nth term is:

a_n = a_1 + (n - 1)d

a_n = -25+ (n - 1)*-14

Open bracket

a_n = -25-14n + 14

Collect like terms

a_n = 14-25-14n

a_n = -11-14n

Find the Length of ST
vfiekz [6]

Step-by-step explanation:

Consider Similarity and enlargement

To get the enlargement factor,

Take the ratio result of any two similar sides. i.e

PQ/AB = 3.6/2 = 1.8

The enlargement factor is 1.8

To get ST, consider ED then multiply it by the enlargement factor. i.e

= 5 x 1.8

= 9
