A cable car travels 2236 m to climb a mountain that is 1000m high. It then travels 1414m to descend 1000m on the other side of the mountain. A tunnel goes straight through the mountain, from the starting pointto the endpoint of the cable car`s journey. How long i the tunnel

, 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

it is only things thain can be deafeated
