a) n² + 6
n=1
1² + 6 = 1 + 6 =7
n=2
2² + 6 = 4 + 6 = 10
n=3
3² + 6 = 9 + 6 =15
n=4
4² + 6 = 16 + 6 =22
7, 10, 15, 22
n=10
10² + 6 = 100 + 6 =106
10 th term-106
b) 3n²
3 x 10² = 3 x 100= 300
10th term- 300
Hope this helps!
Answer:
Option B
Step-by-step explanation:
The value of x is 4/3 .
12.8, 11.6, 10.4, 9.2, 8.0, 6.8, 5.6
3, 1.5, 0.75, 0.375, 0.1875, 0.09375, 0.046875
The first one is arithmetic as the pattern is deducting 1.2, second one is geometric as it is dividing 2.
289
a^2 x b^2 = c^2
a = 8 b= 15 c = s
64 + 225 = 289
square root 289 = 17
