What is the sum of the finite arithmetic series (-5)+0+5+10+ ......+65
Alex17521 [72]

If you want to solve this problem using formulas, there are two important formulas:

t1  =  first term  =  -5          

tn  =  nth term  =  last term  =  -5

n  =  numbr of terms

Sn  =  sum of the n terms

tn  =  t1 + (n - 1)d     --->     65  =  -5 + (n - 1)(5)

                                          65  =  -5 + 5n - 5

                                          65  =  -10 + 5n

                                          75  =  5n

                                            n  =  15

Sn  =  n(t1 + tn)/2     --->     Sn  =  15(-5 + 65)/2

                                          Sn  =  450


So ur answer rounds up to 450

Contains fractions <br> 6v-5/8=7/8
Novay_Z [31]

Answer: v = 2

Step-by-step explanation:

Your equation:

\frac{6v-5}{8}  = \frac{7}{8}

You can multiply both sides by 8 to eliminate the fraction, which gives you this:

6v - 5 = 7

Then, you can solve for it:

6v = 12

v = 2
