Assuming that the numbers are not only consecutive, but **fall in the alphabetical order given.**

Since 116 is the average, and there are 6 numbers given, 3 must fall on either side of 116. That means that the following should be true:

P:111

Q:113

R:115

S:117

T:119

U:121

Therefore the product of R and T, or R * T, would be 115 * 119 **= 13,685.**
