Answer 35

Question 6.
Ask me where you're stuck.

10, 18, 26, 34, 42

T = a + (n-1)d

Where a is the first term.
n is the term you have to find.
And d is the common difference.

Step 1.
Find d.
subtract any 2 adjacent term.
Let's say 42 and 34
42-34 = 8

So d =8

Now insert the values in the formula.

T = a + (n-1)d

Answer 36

I still have to leave. Will do in 10 mins.

Okay. So for "nth" term, there's a formula.

T = a + (n-1)d


Where a is the first term.
n is the term you have to find.
And d is the common difference.

You have to learn this formula.
If you're through till here then i'll move forward.

Answer 53

Okay.

Answer 54

its the same for all of them?

Answer 55

Okay. So what is d?
it's the common difference.

To find it, subtract any two adjacent terms.

Let's say 14 -11 = 3
Hence, d = 3

Answer 56

And yes, it's same for all.

Answer 68

Write it this way:

T_n = a + (n-1)d
= 10 + (n-1)8
= 10 + 8n - 8
= 8n + 2

Next, insert 70 in place of n.
