Which of the following sequences is an arithmetic sequence? 1, 2, 4, 8, 18, ... 10, 12, 14, 16, 18, ... 200, 100, 50, 25, ... 4,

The sequence 10, 12, 14, 16, 18, ... is an arithmetic sequence, with the common difference being 2.
The answer is 51 remainder 4 because 51* 4 =408 and 412 + 4 = 412
(1.2×10^2) + (3.04×10^5)
They must be to the same power to add
3.04 *10^5 to change to the 2nd power (5-2=3) move the decimal 3 places to the right = 3040. * 10^2
1.2 * 10^2 + 3040 *10^2=
add the numbers keep the exponents the same
3041.2 * 10^2
there can only be 1 number before the decimal in scientific notation so we need to move the decimal 3 places to the left, which adds 3 to the exponent
3.0412 * 10 ^ (2+3)
3.0412 * 10^5
The answer is C because since the answer is 4 and if u look at c it would equal to 4.
