Asequence has 3 terms its term to term rule is multiply by 6 and then add 13
a) the first term of the sequence is -2
workout the third term
b) the order of the three terms of the sequence is reversed
describe the term to term rule of the new sequence

a) Third Term = 19

b) Term to Term rule = Subtract 13 and then Divide by 6

Step-by-step explanation:

a)

Since first term is -2, so according to rule, second term is:

second term =

Now, finding the third term with the rule:

Third Term = 19

b)

The first 3 terms of the sequence is -2, 1, 19 ...

If reversed, it is:

19, 1, -2 ....

The rule will also be reversed. So it will be to subtract 13 and then divide by 6.

x=12 units bd= 10 units

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
