Chapter 7: Q 43. (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 of ${\sum a_{k}}_{k = 0}^{\infty}$ .

Short Answer

Expert verified

The value of ${\sum a_{k}}_{k = 0}^{\infty} = 9$ .

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 ${\sum a_{k}}_{k = 0}^{\infty}$ can be obtained as follows.

$\begin{array}{rcl} {\sum a_{k}}_{k = 0}^{\infty} & = & a_{0} + a_{1} + {\sum a_{k}}_{k = 2}^{\infty} \\ = & - 3 + 5 + 7 \\ = & 9 \end{array}$

Therefore, value of $\sum_{k = 0}^{\infty} a_{k}$ is 9.
