Question

Which answer represents the series in sigma notation? −5+(−1)+3+7+11

Answer 1

Answer:

In sigma notation, the series may be represented as,

$\sum_{x = 0}^{4}(-5 + 4x)$

It is an arithmetic progression with

1st term = -5

common difference = 4

no, of terms = 5

Step-by-step explanation:

The finite series is given by,

-5 + (-1) + 3 + 7 + 11

In sigma notation, the series may be represented as,

$\sum_{x = 0}^{4}(-5 + 4x)$

It is an arithmetic progression with

1st term = -5

common difference = 4

no, of terms = 5
