Question

the algebraic expression of an arithmetic sequence is xn=4n+3 .

1)write the first term
2) Write the common difference
3) what is the reminder when the terms are divided by 4​

Answer 1

Answer: Put n= 1 2 3

Step-by-step explanation: Xn=4n+3

X1=4×1+3=7

X2=4×2+3=11

now,

Common difference = X2-X1

= 11-7

= 4

Answer 2

Answer:

xn=4n+3

n=1 , x(1)=4(1)+3

x(1)=4+3

x(1)=7=first term

a=7

n=2 , x(2)=4(2)+3

=8+3

x(2)=11=second term

d=a2-a1

d=11-7

d=4

A1/4=7/4=1.75

A2/4=11/4=2.75
