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

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.

its the same for all of them?
saifoo.khan
Best Response
You've already chosen the best response.
1
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

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.
