Series- Arithmetic - Find the sum of the first 196 terms of 2,7,12,17,.. Please someone help me figure out this problem!

If a1=2, and the distance between your terms is 5, then a196=977 an=a1+(n-1)d where d is the distance. Then, the sum is defined as: n(a1+an)/2 so it will be: 196*(2+977)/2=95942
