Arithmetic

Consider .... 15 + 14N

If N = 1, we have 29 for the first term

If N = 2, we have 43 for the second term

etc.

it is an AP if T_{2} - T _{1} = T _{3} - T _{2} = T _{4} - T _{3} = .... = d

now 43-29 = 57-43 = 71-57 = 14 therefor it is an AP and the common difference is d=14

---------------------------------------------------------------------

If it had been a GP then

T_{2} / T _{1} = T _{3} / T _{2} = T _{4} / T _{3} = .... = r

lydianotauseryet00:Is the following patteren geometric or aritmetic: 29,43, 57, 71

it is an AP if T

now 43-29 = 57-43 = 71-57 = 14 therefor it is an AP and the common difference is d=14

---------------------------------------------------------------------

If it had been a GP then

T
