The number of terms in the sequence: –45, –32, –19, –6, ..., 124 = 9.
The common difference is -45 - (-32)= 13
d = 13.
<h3>What is arithmetic progress?</h3>
AP is a sequence of numbers in order, in which the difference among any two consecutive numbers is a constant cost. it's also referred to as mathematics series.
using arithmetic progress:-
last term = (n-1)d
first term(a) = –45
term = a + (n-1)d
there is a difference of 13, so the sequence will be
–45, –32, –19, –6,7, 20, 33, 46, 59, 72, 85, 98, 111, 124.
∴ number of terms = 9
