Given 7x + 2 ≥ 58, which number is not in the solution set?

i can't see the rest of the question so i don't know the answer choices but:

since x≥8

whichever choice is less than 8 is incorrect

step-by-step explanation:

7x≥56

x≥8

-1, -2, -3, -4, -6

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
