Q:

Use summation notation to write the series 6.6 + 15.4 + 24.2 + ... for 5 terms

Accepted Solution

A:
Answer:For the first five terms of given series  6.6 + 15.4 + 24.2 + ... we can write it as  [tex]\sum _{n=1}^5\left(-2.2+8.8n\right)[/tex]Step-by-step explanation:  Given series  6.6 + 15.4 + 24.2 + ... We have to write the summation notation to write the series  6.6 + 15.4 + 24.2 + ...   for 5 termsConsider the given series  6.6 + 15.4 + 24.2 + ...  We will find a pattern for the  given series 6.6 can be written as (-2.2+8.8(1))15.4 can be written as (-2.2+8.8(2))24.2 can be written as (-2.2+8.8(3))And so on Thus, for the first five terms, we can write it as  [tex]\sum _{n=1}^5\left(-2.2+8.8n\right)[/tex]
