Find the value of 10th and 100th term in 2n +1
​

Answer 1

Answer:

substitute n=0 2n+1=2(0)+1=1

n=1 2(1)+1=3

n=2 2(2)+1=5

a=1

d=3-1=2

t10=a+(10-1)*d

t10=1+9*2

=19

t100=a+(100-1)*d

=1+99*2

= 1+198

=199

Answer 2

Step-by-step explanation:

n-term =2n+1

therefore,

1st term =3

2nd term =5

common difference,d =5-3 =2
