Answer 1

Given Ap

-3,-1/2,2......

a1,a2,a

here first term a=1

and common difference d= a2-a1

=-1/2-(-3)

-1/2+3

=-1+6/2

=5/2

for finding 11 term formula

an=a+(n-1)d

here n=11

then substitute these values in the formulae

a11=-3+(11-1)5/2

a11=-3+(10)5/2

a11=-3+50/2

a11=-3+25

a11=22

11 term of the given Ap is 22
