wstaw między liczby 1 i 25 siedem liczb tak aby otrzymać ciąg arytmetyczny
1, 4,7,10,13,16,19,22, 25
różnica to 3
Proces liczenia:
a1 + 8r = 25
1 + 8r = 25
8r = 24
r = 3
1, ..., ...., ....., ....., ....., ..... ,......, 25
a9 = 25
8r = 25 - 1
1, ..4., ...7., ...10.., ..13..., ...16.., ...19.. ,...22..., 25
