How do i figure out the greatest common factors im a little confused

To find the GCF of two numbers: List the prime factors of each number. Multiply those factors both numbers have in common.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
