Answer 1

Answer:

6th term

Step-by-step explanation:

Given,

A.P : 14, 11, 18, ……………

a = 14

d = 11 - 14 = - 3

l = - 1

To find : n = ?

n = [ ( l - a ) / d ] + 1

= [ ( - 1 - 14 ) / - 3 ] + 1

= [ - 15 / - 3 ] + 1

= [ 15 / 3 ] + 1

= 5 + 1

n = 6

Therefore, the 6th term of A.P 14, 11, 18, …………… is -1.
