Answer:
the first one is 1.935843 x 10^6
the second one is 4 x 10^7
subtract the two numbers in each question

Answer:
Step-by-step explanation:
the formula for an arithmetic sequence is
a, a+d,a+3d,a+3d etc, where d is the common difference
we have the terms -6, 13,23
first term is -6
-6+19=13
however, 13+10=23
this is not an arithmetic sequence
Answer:
-3
Step-by-step explanation:
Point A is half way between -17 and 5. This is span has a total distance of 17 + 5 = 22. Half way is 11 units from -17 or 5. So -17 + 11 = -6.
Point B is halfway between A at -6 and 0. This is a distance of 6. So halfway is 3 units away at -3.
