Given recursive formula is
f(n) = 22 * f(n - 1)
Where first term : f(1) = 10
And we need to find the first five terms of this sequence. So , let's find the second term by plug in n = 2 in the above formula. Therefore,
f (2) = 2.2 * f ( 2 -1)
= 2.2 * f(1)
= 2.2 * 10
= 22
So second term is 22.
Similarly plug in 3 for n to get the third term. Hence,
f(3) = 2.2 * f(3 -1) = 2.2 * f(2) = 2.2 * 22= 48.4
f(4) = 2.2 *f( 4 -1) = 2.2 * f(3) = 2.2* 48.4 = 106.48
f(5) = 2.2* f(5-1)= 2.2 * f(4) = 2.2 * 106.48 = 234.256
So, the first five terms are 10, 22, 48.4, 106.48 and 234.256.
Hope this helps you!

Answer:
= 8√15
Step-by-step explanation:
Steps
2√3 x 4√5
Apply radical rule: √a√b=√ab.
√3 √5 = √3x 5
=2√3x 5 x 4
Multiply the numbers: 3 x 5= 15
=2√15 x 4
Multiply the numbers: 2 x 4 =8
= 8√15
2√3 x 4√5 = 8√15 (Decimal: 30.98386..)
