The sixth term of an A.P is half of its twelfth term. The first term of the A.P is equal to
Answer Details
Let's assume that the first term of the A.P is 'a', and the common difference is 'd'.
We know that for an A.P, the nth term is given by:
a + (n-1)d
According to the problem, the sixth term is equal to half of the twelfth term.
So, we can write:
a + 5d = 1/2 (a + 11d)
Multiplying both sides by 2 to eliminate the fraction:
2a + 10d = a + 11d
Simplifying, we get:
a = d
Therefore, the first term of the A.P is equal to the common difference.
So, the correct answer is "the common difference."
