I found these, all in Webster's 3rd Unabridged: REVIOLATES (common difference = 9) SPONDYLIUM (12) MISSIONARY (15) GERUNDIVES (16) I note that she didn't consider words where the common difference is negative, such as USABLE, which has U=21, S+A=20, B+L+E = 19, forming an arithmetic progression with common difference -1.

[FIGURE 1 OMITTED] Using the sum of an arithmetic progression with common difference 1, it can be shown that the nth triangular number is given by T (n) = n(n + 1)/2 Ask your students to draw the square numbers and write down the formula for them [S(n) = [n.

a) The size of the optotypes in PANEL I is 5x4 but in PANEL II they are 5x5 b) The optotypes follow a logarithmic progression in PANEL I but an arithmetic progression in PANEL II c) There is less crowding with the optotypes in PANEL I compared to PANEL II d) The optotypes in PANEL I are suitable for children under 4 years of age but PANEL II are not 10.

The joint with the open root crack was analyzed, the crack lengths being considered in arithmetic progression, with the ratio 0.

Points P and Q, moving along at different rates in Figure 1, PB decreasing in geometric progression while CQ increases in arithmetic progression, would necessarily fall in the jurisdiction of the mathematics of change, namely calculus.

124," however, contained "4," a number associated with magic in both West African and Western cultures; and instead of a simple arithmetic progression, each successive number in "124 "doubles the preceding number, creating an open-ended geometric progression (Jeanette K.

Social Security, by contrast, is a simple arithmetic progression that "is sustainable forever, provided that the number of new people entering the system maintains a rough balance with the number of people collecting from the system.
