Question

.If a and d are respectively the first term and the common difference of an A.P, a+ 10d, denotes

the _______ term of the A.P​

Answer 1

Answer:

11th

Step-by-step explanation:

${a}^{n} = a + (n - 1)d$

Where n is the term in the A.P.

According to the question, a+10d is the nth term.

So,

$a + (n - 1)d = a + 10d$

$a - a + (n - 1)d = 10d$

$(n - 1) = \frac{10d}{d}$

$n = 10 + 1$

$n = 11$

So, a+10d is the 11th of the A.P.

Or

$n = 11$

${a}^{11} = a + 10d$
