Answer 2

Step-by-step explanation:

Here

First term=2=a

Common difference d=5-2=3

And anth=a+(n-1)d

Now a 37 =a+(37-1)d

=>a 37=2+(36)3

=>a 37=2+108=110

Now s 19=n/2[2a+(n-1)]d

=>s 19=19/2[2×2+(19-1)3]

=>s 19=19/2[4+54]

=>s 19=19/2×58

=>s 19=19×29

=>s 19=551

☆37th term of an A.P is 110.

☆Sum of first 19terms is 551.
