Which expression defines the given series for seven terms? –3 + (–1) + 1 + . .
a.ς (2n-5)
b.ς (2-5n) c.ς (5n-2) d.ς (5-2n)

Step-by-step explanation:

Given: The first term of the series

The second term of the series

The third term of the series

The common difference=

Now, the nth term of this series will be given by :-

Hence, the expression defines the given series for seven terms will be

r and t.

both are 64 degrees.
