Answer:
5(x2 + 3x) = 5(22 + 3
Step-by-step explanation:
Hope it is helpful....
3/20, 6/20, 9/20, 12/20 so the common difference is 3/20, ie each term is 3/20 greater than the term preceding it. Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=initial term, d=common difference, n=term number, in this case:
a(n)=3/20+(3/20)(n-1)
a(n)=3/20+3n/20-3/20
a(n)=3n/20 so the 5th term is:
a(4)=3*5/20=15/20=3/4
Sequence and series are very important.
Because with the help of number sequences and series formulas, you can perform Quantitative Analysis, Financial and Business Analysis to help you in important business and investment decisions.
