Question

Find the sum by adding each term together. Use the summation capabilities of a graphing utility to verify your result.

Answer 1

We are asked to solve the given summation problem.

The summation problem says to add (4i + 5) for i = 1 to 6.

`For\;i=1:\;\;(4*1+5)=4+5=9`
`For\;i=2:\;\;(4*2+5)=8+5=13`
`For\;i=3:\;(4*3+5)=12+5=17`
`For\;i=4:\;\;(4*4+5)=16+5=21`
`For\;i=5:\;(4*5+5)=20+5=25`
`For\;i=6:\;\;(4*6+5)=24+5=29`

Finally, now add them all together.

`9+13+17+21+25+29=64`

Therefore, the given summation problem is equal to 64
