Find the first five terms of the sequence given by a1 = 2, an = 3an-1 - 1

Given the sequence:

where, n is the number of terms.

We have to find the first five terms of the sequence.

For n = 2;

⇒

Substitute the given values we have;

For n = 3

⇒

Substitute the given values we have;

For n = 4

⇒

Substitute the given values we have;

For n = 5

⇒

Substitute the given values we have;

Therefore, the first five terms of the sequence are:

, , ,   and  ,

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
