Question

Please axplane me.... Answer ​

Answer 1

Answer:

answer = 770

Step-by-step explanation:

here in this question we have to put the value of r from r = 1 to r = 10

now

t1 = 2 × (1)^2 = 2

t2 = 2 × (2)^2 = 8

t3 = 2 × (3)^2 = 18

t4 = 2 × (4)^2 = 32

t5 = 2 × (5)^2 = 50

t6 = 2 × (6)^2 = 72

t7 = 2 × (7)^2 = 98

t8 = 2 × (8)^2 = 128

t9 = 2× (9)^2 = 162

t10 = 2 × (10)^2 = 200

when you will add : t1 + t2 + t3 + t4 + t5 + t6 + t7 + t8 + t9 + t10

the reasultant will be = 770

Hope you find it useful !!!!
