Question

the third term of an arithmetic sequence is 35 and the 6th term is 68 what is its 85th term​

Answer 1

Answer:

the answer is will be 8th term

Answer 2

Answer:

937 is the 85th term.

Step-by-step explanation:

we know that nth term of an arithmetic sequence is a+(n-1)d

therefore,

3rd term= a+(3-1)d

6th term= a+(6-1)d

when the equations are subtracted,

_ a+2d=35

a+5d=68

-3d= -33

d=11

a+2d=35

a+22=35

a=13

85th term=a+(85-1)d

13+(84)11

13+924

=937

Hope that helps!
