Question

The the algebraic form of an arithmetic sequence is 4n +1
a.what is it's common difference.
b.what is it's first term
c.what is the reminder when each term of this sequence is divided by 4.​

Answer 1

Answer:

Hi ❤️,

first of all put n=1&n=2

After that you will get 5 and 9 respectively.

like this 4n+1

n=1, 4(1)+1= 5 ( first term of A.P)

n=3, 4(2)+1=9

now (A) Common difference= 9-5=4

(B) 1st term is 5 we have already solved

(C) it's 1 ( divide 5 by 4 and 9 by 4 we'll get 1 as remainder)

hope I helped u !!!

Actually I solved this on a seperate paper to attach dear but my bad luck only camera is not working in phone so I tried my best to make you understand through typing also. ;)
