Answer:
Step-by-step explanation:
t=number of terms
a=first term in a given sequence.
d=common difference
the 16th term of an a.p is 93 and the common difference is 6. find the first and 28th terms.
by finding the first and the 28th term we use the formula for a.p which is:
tn=a+(n-1)d
T16=a+(16-1)6
93=a+15*6
93=a+90
collect like term
a=93-90
a=3
the first term of a.p is 3
* find the 28th term
tn=a+(n-1)d
t28=3+(28-1)6
=3+27*6
=3+162
=165
the 28th term of a.p is 165.
