an increase of 5% $\langle$a 5% increase$\rangle$ in the cost of living
A small percentage reduction in the cost of materials resulted in a significant increase in profit.
a considerable $\langle$major/marked/ significant/substantial/modest/small/sharp/steady/sixfold/overall$\rangle$ increase
Obviously, $G_n$ increases to $G$ as $n\to\infty$.
Sales increased almost fourfold in this period.
The budget has increased by more than a third.
We adopt the convention that the first coordinate $i$ increases as one goes downwards, and the second coordinate $j$ increases as one goes from left to right.
The index increases by 1 when the path is crossed from right to left.
The numbers inserted in $L$ must increase strictly down each column.
Also, $F$ does not increase distances.
There has recently been increasing interest in the theory of ......
It becomes impracticable to compute the zeros of $F$ for degrees greater than 6; in any event, deciding whether the divisors found in this way represent irreducible curves becomes increasingly difficult.
Indeed, as $n$ increases, it becomes increasingly rare for a manifold to be a hyperplane section of another projective manifold.
