Answer 1

Answer:

Step-by-step explanation:

8th answer

sn=2n2+2

putting value of n as 1

s1=2*(1)2+3=5

putting n as 2

s2=2*(2)2+3*2=14

putting n as 3

s3=2*(3)2+3*3=27

subtract s2 from s1 to get a2

s2-s1=14-5=9

9=a2

sub s3-s2=27-14=13

so the a.p formed is 5,9,13

a=5

d=4

then find the term by an=a+n-1*d
