Question

find TN if a=3 and d= -3​

Answer 1

Answer:

6-3n

Step-by-step explanation:

Given - a =3

           d=-3

To find - Tn=?

Solution-

We know that  Tn = a + (n - 1)d.

∴Tn = 3 + (n - 1)× -3

      =3 +-3n+3

      =6-3n

Answer 2

Step-by-step explanation:

$a = 3 \\ d = - 3 \\ \\ T_{n} = a + (n - 1)d \\ T_{n} = 3 + (n - 1) - 3 \\ T_{n} = 3 + ( - 3n) + 3 \\ T_{n} = 3 - 3n + 3 \\ T_{n} = - 3n + 6 \\ T_{n} = \underline{ \underline{ - 3(n - 2)}}$
