Question

Find the 16th term of AP

14 , 9 , 4 , - 1 , - 6

Answer 1

a=14
d=-5
n=16
a16=a+15d = 14+(15*-5)=14-75=-61

Answer 2

HOLA

==================

Tn = A + (n - 1) D

Here , A = 14 and D = - 5

T 16 = 14 + ( 16n - 1) - 5

T 16 = 14 + (15n) - 5

T 16 = 14 + ( - 75n)

T 16 = - 61

So the 16th term is - 61
