Which answer is the explicit rule for the sequence 5,11,17,23, ?

an=1−6n

an=−1−6n

an=1+6n

an=−1+6n

an = 6n-1

Step-by-step explanation:

5,11,17,23,29...

If you look at the difference between each term, we are adding 6 each time

11-5 =6,  17-11 =6,  23 -17 =6

The formula for a sequence is

an = a1 + d(n-1)

a1 is 5 and d =6

an= 5 + 6(n-1)

an = 5+6n -6

Combine like terms

an = 6n-1

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.
