Question

If first term and common difference of an ap are 6 and 7 respectively then find 12th term

Answer 1

Answer:

83

Step-by-step explanation:

In APs, nth term = a + (n - 1)d, where a is first term and d is common difference.

Here,

a = first term = 6

d = common difference = 7

12th term = a + (12 - 1)d

= > 6 + (12 - 1)7

= > 6 + (11)7

= > 6 + 77

= > 83

Answer 2

Given:-

First term, a = 6

Common difference, d = 7

To find:-

a₁₂

Formula:-

aₙ = a + (n-1) d

Solution:-

a₁₂ = a + 11d

a₁₂ = 6 + 11×7

a₁₂ = 6 + 77

a₁₂ = 83

Answer:-

a₁₂ = 83
