Question

Find tn if a=20 and d=3
​

Answer 1

Answer:

Given:-

a=20

d=3

Step-by-step explanation:

We know,

tn=a+(n-1)d

Now,

Now,tn = a + (n -1 ) x d.

Now,tn = a + (n -1 ) x d.tn = 20 + ( n - 1) x 3.

Now,tn = a + (n -1 ) x d.tn = 20 + ( n - 1) x 3.tn = 20 n x 3.

Now,tn = a + (n -1 ) x d.tn = 20 + ( n - 1) x 3.tn = 20 n x 3.tn = 60 / n.

Now,tn = a + (n -1 ) x d.tn = 20 + ( n - 1) x 3.tn = 20 n x 3.tn = 60 / n.tn = 60.

Answer 2

Answer:

tn=3n+17

Step-by-step explanation:

tn=(a+(n-1)D)

tn=20+3n-3

tn=3n+17
