Question

answer the following questions based on the given pattern 1=1 1+3=4 1+3+5=9.... a)write the next two terms b)find the sum of first 15 odd nos c)find 1/2+3/2+5/2,.... 29/2,....​

Answer 1

Step-by-step explanation:

given pattern 1=1 1+3=4 1+3+5=9

a) the next two terms

1+3+5+7=16

1+3+5+7+9=25

b) the sum of first 15 odd nos = 15^2 = 225

c) 1/2+3/2+5/2+....+29/2+....+n/2

= (1+3+5+...+n)/2

= (n^2)/2
