How do you find how many terms this has if the lower limit is k=b and the upper limit is b+12, i know you subtract them and add 1, but i'm not sure how to do it with this

Can you please help

Thanks

not sure how this is typed on here but i'll try and explain it

sigma sign, on the top is b+12 and on the bottom is k=b, and the equation is 3n-7 - June 8th 2010, 10:42 PMProve It
