Question

is 10, 12, 22, 32, 42, . . .a geometric or arithmetic sequence?

Answer 1

Are you certain that 10 is the first term?

Answer 2

yes

Answer 3

yeah something's
not right here

Answer 4

maybe its neither right?

Answer 5

From 12 on I'd say +10 so arithmetic. But 10 and 12 doesn't fit...so neither?

Answer 6

It is certainly neither. It would be arithmetic (adding 10 each time) except for that first term.

Answer 7

thanks!
