To find the next number in the sequence: 6, 9, 12, 15, of the following? you would need to do which of the following. A subtract 3 from 15
B subtract 3 from 6
C add 3 to 15
D add 12 to 15
or None

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
