Answer:
4800, 5900
Explanation:
Looks like you add 1100 to each term to find the next term.
1500 + 1100
is 2600 (the second term)
and then 2600 + 1100 is 3700 (the 3rd term)
so continue,
3700 + 1100 is 4800
and then 4800
+1100
is 5900.
Three terms is not much to base your answer on, but +1100 is pretty straight forward rule. Hope this helps!
