So many of these same type of problems!
term4 = a + 3d = 24
term12 = a + 11d = 56
subtract:
8d = 32
d = 4
then a + 12 = 24
a = 12
use the same definition I just used to find term28
term4 = a + 3d = 24
term12 = a + 11d = 56
subtract:
8d = 32
d = 4
then a + 12 = 24
a = 12
use the same definition I just used to find term28
