What is the second term of the arithmetic series in which a1 = 4, an = 106, and Sn = 990?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4
