You need to force evaluation of the second argument of NIntegrate prior of
using it since NIntegrate which has the attribute HoldAll.
All the following possibilities return 702. (as expected)
NIntegrate[Evaluate[r, {r, 14, Sequence @@ {16, 18}, 40}]]
NIntegrate[r, Evaluate@{r, 14, Sequence @@ {16, 18}, 40}]
NIntegrate[r, Evaluate[{r, 14, Sequence @@ {16, 18}, 40}]]
NIntegrate[r, {r, 14, Sequence @@ {16, 18}, 40} // Evaluate]
