Need to find the sum of 50

Mathematics
1 answer:
Bumek [7]3 years ago
6 0

Answer:

4600

Step-by-step explanation:

This is an arithmetic sequence with common difference d between consecutive terms.

d = - 2 - (- 6) = 2 - (- 2) = 6 - 2 = 4

The sum to n terms of an arithmetic sequence is

S_{n} = \frac{n}{2}[ 2a + (n - 1)d ]

where a is the first term

here a = - 6, d= 4 and n = 50, hence

S_{50} = \frac{50}{2} [ (2 × - 6) + (49 × 4) ]

                           = 25 ( - 12 + 196 )

                           = 25 × 184

                           = 4600

All you have to do is divide the number by the denominator which is 8. So 510 divided by 8.

Which will give you 63.75.

Then you times it by the numerator which is 3 so 63.75 x 3

And you are left with £191.25 which is 3/8 of 510
