ANSWER:
Given:
- AP = 3, 3+√2, 3+2√2, 3+3√2
To Find:
- Next term of the AP
Solution:
We are given that, the AP is:
⇒ AP = 3, 3+√2, 3+2√2, 3+3√2
We know that, in an AP,
⇒ a2 - a1 = a3 - a2. . . . . = d(common difference)
So, the common difference is,
⇒ a2 - a1 = 3+√2 - 3
⇒ d = √2
Now,
We will add the common difference to the last given term so as to find the next term in the series.
Hence,
⇒ Next term = 3+3√2 + √2
⇒ Next term = 3 + 4√2
Therefore, the next term of the AP is 3 + 4√2.
