Question

for an A. P. .., a = 20 , d =4, find tn​

Answer 1

Answer:

The tn term is 16 + 4n.

Step-by-step explanation:

tn = a + (n -1)d

tn = 20 + (n -1)4

tn = 20 + 4n - 4

tn = 16 + 4n

Therefore, the tn is 16+4n.

Answer 2

Answer:

$a = 20 \\ d = 4 \\ \\ T_{n} = a + (n - 1)d \\ T_{n} = 20 + (n - 1)4 \\ T_{n} = 20 + 4n - 4 \\ T_{n} = 4n + 16 \\ T_{n} = \underline{ \underline{ 4(n + 4)}}$
