MCQ
A series can also be denoted by symbol $.........$
  • A
    $\pi\text{a}_\text{n}$
  • ✓
    $\sum\text{a}_{\text{n}}$
  • C
    $\phi\text{a}_{\text{n}}$
  • D
    $\theta\text{a}_{\text{n}}$
✓

Answer

Correct option: B.
$\sum\text{a}_{\text{n}}$
When we use addition between the terms of sequence, it is said to be series.
We know that addition can also be written in the form of sigma
so, series can also be denoted by $\sum\text{a}_{\text{n}}.$
