an=n+1/n2+3
then
find
a2-a3/a4-a5​

Answer 1

Answer:

532/273 = 1.95

Step-by-step explanation:

aₙ=n+1/n²+3

a1=(1+1)/1+3)=2/4=1/2

a2=(2+1)/( 2²+3)=3/7

a3=(3+1)/(9+3)=4/12=1/3

a4=(4+1)/(16+3)=5/19

a5=(5+1)/(25+3)=6/28=3/14

Now

(a2-a3) / (a4-a5)

=(3/7-1/3) /(5/19-3/14)

={(9-7)/21} / { (70-57)/14*19 }

=2 /21 * 14*19/13

=2*14*19/21*13

=532/273

=1.95
