4y^2=(2y)^2
16=4^2

If you factor the denominator of the left multiplicand...

[(a-4)(a+3)]/[a(a-4)] you can see that the (a-4)s cancel out leaving:

(a+3)/a

now you have

(a+3)/a * 2a^3/((a+3)(a-1)) so the (a+3)s cancel out leaving:

1/a * 2a^3/(a-1) which is:

2a^3/(a(a-1)) so now a^1 cancel leaving

2a^2/(a-1)

A sequence {an} is generated by the recursive formulas a1 = 5 and an = an-1 + 5(-1)n. Find, a343, the 343rd term of the sequence

Olenka [21]

$a_n=a_{n-1}+5(-1)^n\\\\if\ n\ is\ even\ then:a_n=a_{n-1}+5(-1)^n=a_{n-1}+5\\\\if\ n\ is\ odd\ then:a_n=a_{n-1}+5(-1)^n=a_{n-1}-5\\\\a_1=5\\a_2=5+5=10\\a_3=10-5=5\\a_4=5+5=10\\a_5=10-5=5\\\vdots\\a_{343}=5\ \ \ \ (343\ is\ odd\ number)$
