Chapter 7: Q 45. (page 615)

Given that $a_{0} = - 3, a_{1} = 5, a_{2} = - 4, a_{3} = 2$ and ${\sum a_{k}}_{k = 2}^{\infty} = 7$ , find the value ofrole="math" localid="1648828803227" ${\sum a_{k}}_{k = 3}^{\infty}$ .

Short Answer

Expert verified

The value of ${\sum a_{k}}_{k = 3}^{\infty}$ is 11.

Step by step solution

Step 1. Given information.

Given that $a_{0} = - 3, a_{1} = 5, a_{2} = - 4, a_{3} = 2$ and ${\sum a_{k}}_{k = 2}^{\infty} = 7$ .

Step 2. Express the series in terms of known values.

Value of ${\sum a_{k}}_{k = 3}^{\infty}$ can be obtained as follows.

$\begin{array}{rcl} {\sum a_{k}}_{k = 3}^{\infty} & = & {\sum a_{k}}_{k = 2}^{\infty} - a_{2} \\ = & 7 - (- 4) \\ = & 7 + 4 \\ = & 11 \end{array}$

Therefore, value of ${\sum a_{k}}_{k = 3}^{\infty}$ is 9.
