Answer 1

Hi...☺

Here is your answer...✌

GIVEN,

AP : 8,11,14,17,....

a = 8 , d = 11-8 = 3

n = ?

Tn = 758

a+(n-1)d = 758

8+(n-1)3 = 758

3n-3 = 758-8

3n = 750+3

3n = 753

n = 753/3

n = 251

HENCE,

758 is 251th Term of Given AP.

Answer 2

a=8
d=3
an=758
an=a+(n-1)d
758=8+(n-1)3
758=8+3n-3
758-8+3=3n
753=3n
753/3=n
251=n
