a) 75+ 100 = 175
175 + 100 = 275
275 + 100 = 375
375 + 100 = 475
475 + 100 = 575

b) 1000 + 250 = 1250
1250 + 250 = 1500
1500 + 250 = 1750
1750 + 250 = 2000
2000 + 250 = 2250

c) 500 - 50 = 450
450 - 50 = 400
400 - 50 = 350
350 - 50 = 300
300 - 50 = 250

d) 25 * 2 = 50
50 * 2 = 100
100 * 2 = 200
200 * 2 = 400
400 * 2 = 800

25 * 2 + 1 = 51
