Question

the Nth term of any parallel series is (2n-1) find it's 7th term​

Answer 1

Step-by-step explanation:

by putting n = 7

so

7th term is 13

Answer 2

Answer:

nth term = 2n - 1

1st term = 2(1) - 1

= 2-1

= 1

2nd term = 2(2) - 1

= 4 - 1

= 3

Common difference, d = 2nd term - 1st term

= 3 - 1

= 2

a7 = a + 7d

= 1 + 7(2)

= 1 + 14

= 15
