Question

PLEASE HELP!
Write the first ten terms of a sequence whose first term is -10 and whose common difference is -2.

Answer 1

it;s simple all u have to do is
take the first term as (-10)

then keep adding ( -2)
u will get the terms...
( -10 ) , [ (-10) + (-2) ] ..... so on

where u will get
(-10) , (-12) , (-14) ....

Got it :) ?

Answer 2

is this arithmetic or geometric ?

Answer 3

Common difference is the difference between any 2 consecutive terms. So, to get the next term you just add (-2).

Answer 4

if it's geometric there will be a common ration not a common difference ...

Answer 5

oh...ok...thanks

Answer 6

You can check whether the common difference is (-2) or not by subtracting the next term from the just preceding term, so as to not make any careless mistakes. Hope this helps.
