Answer 1

Answer:

a15 = 70

Step-by-step explanation:

a3 = 10 ( given)

a3 = a + 2d (1)

10 = a + 2d (1)

a5 = 20 ( given )

a5 = a + 4d (2)

20 = a + 4d (2)

Now, subtract (1) from (2)

20 = a + 4d

10 = a + 2d

- = - -

10 = 2d

10/2 = d

5 = d

Now, put d = 5 in (2)

20 = a + 4(5)

20 - 20 = a

0 = a

therefore, a15 = a + 14d

a15 = 0 + 14(5)

Ans: a15 = 70
