Question

Find the 5th term of the arithmetic sequence if T3 = 4 and d = 4.

Answer 1

$d = 4 \\ \\ t3 = 4 \\ \\ a + 2d = 4 \\ \\ a + 2(4) = 4 \\ \\ a + 8 = 4 \\ \\ a = 4 - 8 \\ \\ a = - 4 \\ \\ t5 = a + 4d \\ \\ = - 4 + 4(4) \\ \\ = - 4 + 16 \\ \\ = 12$

Answer 2

Answer:

t5 = 12

Step-by-step explanation:

d = 4

t3 = 4

a + 2d = 4

a + 2(4) = 4

a + 8 = 4

a = -4

t5 = a + 4d

-4 + 4(4)

-4 + 16

12

t5 = 12
