## Problem 595

Find the 5^{th} term of the sequence in which t_{1} = 8 and t_{n} = -3t_{n-1.}

_{ }Solution:-

t1 = 8

t2 = -3(t1) = -3(8) =-24

r = -3

a5 =

a5 = 648

## Problem 590

Find S_{10} for the series 2 + 7 + 12 + 17 +…

**Solution:-**

a1 = 2, d = 5

S_{10} = [2*a1 + (n-1)*d]

S_{10} = [2*2 + (10-1)*5]

S_{10} = 245
