Hello I Dont Know If You Can Help Me With This class=

Sagot :

we have that

In this problem we have an arithmetic sequence

the general equation is equal to

an=a1+D(n-1)

where

a1 is the first term

D is the common difference

n is the number of terms

so

a1=7

D is the difference between consecutive terms

D=11-7=4

an=7+4(n-1)

change the variables

d=7+4(n-1)

d=7+4n-4

d=4n+3

For n=30

d=4(30)+3

d=123
