please helpConsider the infinite geometric series below.

a. Write the first 4 terms of the series

b. Does the series diverge or converge?

c. If the series has a sum, find the sum.

[infinity] n−1 ∑ (−2)

n=2

in you can do this I will give brainily

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
