Answer 1

$\large{\rm{\underline{\underline{Answer:}}}}$

a) n² + 6

~Here n is the number of term. So, put n = 1,2,3,4.... to get the term.

• If n = 1, first term = 1² + 6 = 7
• n = 2, second term = 10
• n = 3, third temm = 15
• n = 4, fourth term = 22
• n = 10, tenth term = 106

b) 3n²

• If n = 1, first term = 3
• n = 2, second term = 12
• n = 3, third term = 27
• n = 4, fourth term = 48
• n = 10, tenth term = 300
