Hi guys, please can anyone give me a hand with this problem? A signal from a mobile phone mast can be picked up by a mobile phone no more than 10 miles away. the circumference of the mobile phone reception has to be at least 55 miles. Find the range of values , to 1 decimal place, for the distance from the mast that a user would have to be able to receive a signal on their phone

thanks in advance

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

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
