Find the first six terms of the sequence.

a1 = -9, an = 4 • an-1

The first six terms of the sequence = {-9, -36, -144, -576, -2304, -9216}

Step-by-step explanation:

Given: a1 = -9, an = 4 • an-1

First term a1 = -9 and the common difference (d) = 4

a1 = -9

a2 = -9*4 = -36

a3 = -36*4 = -144

a4= -144*4 = -576

a5 = -576*4 = -2304

a6 = -2304*4 = -9216

Therefore, the first six terms of the sequence = {-9, -36, -144, -576, -2304, -9216}

Hope this will helpful.

Thank you.

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
