Answer 1

ANSWER:

1,3,5,7

Step-by-step explanation:

if u start frm n=0 then ,a0=1

n=1 thn a1=3

n=2 then a2= 5

Answer 2

Concept

A series of numbers is called a "arithmetic progression" (AP) when any two subsequent numbers have a constant difference. Arithmetic Sequence is another name for it.

Given

$An=2n+1$

To Find

We have to find the first four terms of the sequence.

Solution

According to the problem,

The equation is given as $An=2n+1$

First term of the sequence = $2*1+1=2+1=3$

Second term of the sequence $=2*2+1=4+1=5$

Third term of the sequence $=2*3+1=6+1=7$

Fourth term of the sequence $=2*4+1=8+1=9$

Hence, four terms of the given AP is $3,5,7,9$.
