Question

Which term of the AP 54, 50, 46,.... is 2?

Answer 1

Answer:

Step-by-step explanation:

a = 54, d = 50 - 54 = -4.

We know nth term is given by Tₙ = a + (n - 1 )d

Tₙ = 2

=> 54 + (n - 1) (-4) = 2

=> 54 - 4n + 4 = 2

=> 58 - 4n = 2

=> 56 = 4n

=> n = 56/4 = 14.

Thus the 14th term of the AP series is 2.

Answer 2

Answer:

14th term of ap will be 2

Step-by-step explanation:

an=a+(n-1)d

2=54+(n-1)-4

2=54-4n+4

2=58-4n

4n=58-2

4n=56

n=56÷4

n=14
