Question

if the 2nd term of an ap is 8 and 5th term is 17find it's 19th term​

Answer 1

Answer:

second term (a2) = 8

fifth term (a5) = 17

we know that general formula of a term in ap is a+(n-1)d  

therefore, a2=a+d    8=a+d

a5=a+4d     17=a+4d

solving the two equations simultaneously....

we get....d=3

therefore, a=5

thus the 19th term (a19) = a+18d = 5 + 18x3 = 5 + 54 = 59
