Question

Express this series using SIGMA NOTATION (under x):
5 + 9 + 13 + 17+ . . . + 101

Answer 1

Sigma notation works as follows:

The value on the top of the
`\Sigma\\` is the last value of x, the value on the bottom (marked as x = value) is the starting value. The term to the right side of the sigma is what gets summed iteratively until x = the last value specified.

In this case x = 5 would be the starting value, x+4 would be the right side value, and 97 would be the top value since 101-4 = 97. If we used 101 the max value outputted would be 105.

The final answer is attached.
