Answer 1

Explanation:

nth term = a+(n-1)d

a is the first term

d is the distance between the terms

and n is the number of terms

now for the 94th term

d = 31 - 25 = 6

a = 25

25 + ( (94 - 1) * 6 )

answer = 583

Answer 2

Hi,

Explanation:

`u_1=25\ first\ term \\u_2=31\\common\ difference=u_2-u_1=31-25=6\\u_3=u_2+6=31+6=37\\\\u_(94)=u_1+(94-1)*6=25+6*93=583`
