C-13-Q046mediumsingle_mcq

If first term $a$ , last term $p$ and number of terms $n$ are known, the sum of an arithmetic series is —

a $\dfrac{n}{2}(a + p)$
b $\dfrac{n}{2}(a - p)$
c $n(a + p)$
d $\dfrac{1}{2}(a + p)$

ব্যাখ্যা

When the first term $a$ , last term $p$ , and number of terms $n$ are known, the sum is the average of the first and last terms times the count: $S=\dfrac{n}{2}(a+p)$ .
