Solution
Here 10th term =35
Rule = Add 3 to get the previous term to get the next term.
This is an Arithmetic sequence, where the common difference (d) = 3
Let's take the first term = a
2nd term = a + d
3rd term = a + 2d
4th term = a + 3d
and so on.
10th term = a + 9d
The 10th term is 35. So 35 = a + 9(3) [d = 3]
Now let's find the value of a (first term)
35 = a + 27
a= 35 - 27
a = 8
We have to find the 5th term.
5th term = a + 4d
5th term = 8 + 4*3 = 8 +12 = 20
Answer: 20.
Thank you. :)
