Please help. 10 points. Identify the common difference OR common ratio, depending on whether the sequence below is arithmetic or geometric. Then use the appropriate formula to write a rule for the sequence. Finally, use the rule to find the tenth term in the sequence. –15, –9, –3, 3, 9, ...

hope this helps! please mark brainliest

Step-by-step explanation:

The COMMON DIFFERENCE is 6

so it's a arithmetic sequence.

The formula is an = a1 + (n-1)d

to find the 10th term: a10 = -15 + (10-1)6

the 10th term is 39

*a1 = the 1 is supposed to go underneath it but can't type it on computer

*an = the n is supposed to go underneath it also

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )
