mark me brainliest please.

Answer 2

Step-by-step explanation:

a= 2

d=5-2 = 3

sum of terms =60100

Sn=n/2(2a+(n-1)d

60100=n/2(2(2)+3n-3)

120200=4n+3n2-3n

0=3n2+n-120200

=3n2+601n-600n-120200

=n(3n+601)-200(3n+601)

=(n-200)(3n+601)

= n= 200

= n= -601/3(rejected because the number of terms would not be negative and not be in fraction

The total number of terms = 200
