Answer 1

Hey user !!

Here is your answer !!

_________________________________________⭐

↪a + d = 8

↪a + 4 d = 17

↪Subtracting both equations we get

↪a + d -( a + 4 d) = 8 -17

↪a + d - a - 4 d = - 9

↪- 3 d = -9

↪d = 3

↪Put value of d in

↪a + d = 8

↪a + 3 = 8

↪a = 8 -3

↪a = 5

↪a + 18d

↪5 + 18 ( 3)

↪5 + 54

↪59 is the 19th term

Hope it is satisfactory :-)
