Question

There are 11 teams in an AP the value of the middle most term is 30.find the sum of all AP​

Answer 1

➤ Answer

330 is the required answer.

➤ Basis

☆ Arithmetic Mean

The arithmetic mean of two terms is the mid-term in an A.P.

➤ Reason

The arithmetic mean of extremes is equal to the middle term, which is 30.

Hence, the sum of all terms is 330.

➤ More information

☆ A.M and A.P

The arithmetic mean of two terms is the mid-term of an A.P.

It is given as $\dfrac{a+b}{2}$.

☆ G.M and G.P

The geometric mean of two terms is the mid-term of a G.P.

It is given as $\sqrt{ab}$. (However, the negative G.M should be considered as well.)

☆ H.M and H.P

The harmonic mean of two terms is the mid-term of an H.P.

It is given as $\dfrac{2ab}{a+b}$.

Answer 2
