Answer 2

Answer:

$\underline{ \underline { \huge \red{\mathbb{ANSWER}}}}$.

Multiples of 3 between 20 and 205 are:

21,24,27,........,204

This sequence forms an AP. with first term a=21 , common difference d=24−21=3 and last term l=204

Since, l=a+(n−1)d

⇒204=21+(n−1)3

⇒204−21=(n−1)3

⇒183=(n−1)3

⇒61=n−1

⇒n=62
