PLEASE HELP ME WITH THIS ALGEBRA QUESTION

The first four terms of the sequence are: {-10,-23,-62,-179}

Step-by-step explanation:

Given recursive formula is:

First term = a1 = -10

The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.

Putting n=2

Putting n=3

Putting n=4

Hence,

The first four terms of the sequence are: {-10,-23,-62,-179}

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
