Determine whether each sequence is arithmetic or geometric. Find the next three terms.
1.
14, 19, 24, 29, . . . (1 point)
geometric, 34, 39, 44
arithmetic, 32, 36, 41
arithmetic, 34, 39, 44 **
The sequence is neither geometric nor arithmetic.
2.
–4, 8, –16, 32, . . . (1 point)
arithmetic, 64, 128, 256
geometric, –64, 128, –256 **
geometric, –48, 64, –80
The sequence is neither geometric nor arithmetic.
3.
81, 27, 9, 3, . . . (1 point)
arithmetic, 0, –3, –6
geometric, 0, –3, –6
geometric, 1, onethird, oneninth

#5 , AS , common difference is 8
so next 3 terms
2 , 10, 18
the others are correct
