Answer 2

Answer:

Step-by-step explanation:

$\boxed{\tt{ Required \ Answer}}$

Given that:-

The first term is 5

The common difference is 6.

We need to find the first 5 terms of the Arithmetic Progression.

Let's Do!

We need to know that:-

$\sf{a_n = a + (n-1)d}$

Where a_n is the nth term.

Where a is the first term

And, n is the number if terms, followed by d, the common difference.

$\sf{a_n = a + (n-1)d}$

$\sf{a_n = 5 + (5-1)6}$

$\sf{a_n = 5 + 4 \times 6}$

$\sf{a_n = 5 + 24}$

$\sf{a_n = 29}$

So, we got the 5th term as 29.

So, the other terms will be 23, 17, 11, 5.

And the required sequence is :-

29,23,17,11, 5 is the answer.
