Answer 2

Answer:

Here, (i)=The number of the terms (n) is 16 and The sum of the terms(Sn) is 440.

Step-by-step explanation:

Here, As per our given question,

=(i)=a=5,d=3,an=50

At first n, an =a +(n-1)×d

=50=5+(n-1)×3

=50=5+3n-3

=50=3n+2

=3n=50-2

=n=48/3

=n=16

So, Here The number of terms(n) is 16.

Now, Sn=n/2[2a+(n-1)×d]

=Sn=16/2[2×5+(16-1)×3]

=Sn=8[10+45]

=Sn=8×55

=Sn=440

So, The sum of the terms in the given A. P.

is 440.
