Question

the first three terms of an AP are 3a-1, 3a+5 and 5a+1 respectively. Then value of a will be?​

Answer 1

Answer:

since its an AP series

Therfore common difference is same

so

3a + 5 - 3a + 1 = 5a + 1 - 3a - 5

6 = 2a - 4

2a = 10

a = 5

Answer 2

Step-by-step explanation:

(3a+5)-(3a-1)=(5a+1)-(3a+5)

3a+5-3a+1=5a+1-3a-5

6=2a-4

2a=10

a=5
